7 Detailed Description
7.1 Overview
The DLPA300 is a micromirror driver for the 9-μm pixel family of DMDs. These include the DLP780NE,
DLP800RE. DLP780TE, DLP781NE, DLP781TE, DLP801RE and DLP801XE DMDs. The DLPA300 micromirror
driver generates VOFFSET and VBIAS voltages required by the DMD. VRESET for the DMDs is generated by an
external voltage regulator. Under the control of the DLPC4430 (or DLPC4420) display controller, the DLPA300
micromirror driver switches these three voltage supplies to control the micromirror reset waveform via the
MBRST pins on the DMD.
Reliable function and operation of the DLPA300 micromirror driver require that it is used as part of the family of
9-μm pixel DMD chipsets. For LED and RGB direct laser illumination, the DLPA100 can be replaced by discrete
power supply ICs and a power supply sequencer.
The DLPA300 consists of three functional blocks: a high-voltage power supply function, a DMD micromirror clock
generation function, and a serial communication (SCP) function.
The high-voltage power supply function generates two specialized voltage levels: VBIAS (21-V) and VOFFSET (10-
V). The exact values are controlled by the DLPC4430 or DLPC4420 display controller. VRESET is generated by
external voltage regulator.
The micromirror clock generation function uses the two voltages generated by the high-voltage power supply
function and the one generated by the external voltage regulator to create the fifteen micromirror clock pluses
(output the OUT[0:14] pins of the DLPA300). OUT15 is unused.
The serial communication function allows the display controller to control the generation of VBIAS, VRESET, and
VOFFSET; control the generation of the micromirror clock pulses; and control the general operation of the
DLPA300 micromirror driver.

7.3.2 Bias Voltage Boost Converter
The bias voltage converter is a switching supply that operates at 1.3 MHz. The converter supplies the internal
bias voltage for the high voltage FET switches. The VBIAS voltage level for the 9-μm pixel family of DMDs is
21V. The VBIAS voltage level is configured by the DLP display controller chip over the serial communication port
(SCP). Four control bits select the voltage level while a fifth bit is the on/off control. The module provides two
status bits to indicate latched and unlatched status bits for under-voltage (VUV) and current-limit (CL) conditions.

7.3.5 Serial Communications Port (SCP)
The SCP is a full duplex, synchronous, character-oriented (byte) port that allows exchange of data between the
DLPC4430 or DLPC4420 display controller, and the DLPA300 micromirror driver (and other DLP devices). The
display controller is the primary on the SCP bus. The DLPA300 micromirror driver is the secondary on the SCP
bus.

8 Application and Implementation
备注
以下应用部分中的信息不属于TI 器件规格的范围,TI 不担保其准确性和完整性。TI 的客 户应负责确定
器件是否适用于其应用。客户应验证并测试其设计,以确保系统功能。
8.1 Application Information
DMDs are spatial light modulators which reflect incoming light from an illumination source to one of two
directions, with the primary direction being into a projection or collection optic. Each application is derived
primarily from the optical architecture of the system and the format of the data coming into the DLP display
controller. Typical applications using the DLP780NE, DLP800RE and DLP780TE chipsets include laserTVs,
smart projectors, enterprise projectors and digital signage. The DLP781NE, DLP781TE, DLP801RE and
DLP801XE are used in higher brightness applications such as ProAV and large venue projectors.
DMD power-up and power-down sequencing is strictly controlled by the DLP display controller through the
DLPA300. Refer to Power Supply Recommendations section in the DLP780NE, DLP780TE, DLP800RE,
DLP781NE, DLP781TE, DLP801RE and DLP801XE datasheets for power-up and power-down specifications. To
ensure reliable operation, the DLP780NE, DLP800RE, DLP781NE and DLP801RE DMDs must always be used
with DLPC4430 display controller, a DLPA100 power management and motor driver and a DLPA300 micromirror
driver. The DLP780TE, DLP781Te and DLP801XE DMDs must always be use with the DLPC4420 display
controller, the DLPA100 power management and motor driver and a DLPA300 micromirror driver. For LED and
RGB direct laser illumination, the DLPA100 power management and motor driver can be replaced with discrete
power supplies that are sequenced to meet the display controller power supply sequencing.
8.2 Typical Application
The DLPA300 micromirror driver controls the switching of the bias, offset and reset voltage levels on the MBRST
pins to assure correct DMD operation. It is a controlled by a DLP display controller which synchronizes the
display data sent to the DMD with the correct sequencing of the bias, offset and reset voltage levels by the
DLPA300 micromirror driver. The typical application shown in 图 8-1 is a Full-HD display using the DLP780NE
chipset. The application is the same for the DLP800RE, DLP781NE or DLP801RE/DLPC4430 chipsets and the
DLP780TE, DLP781TE or DLP801XE/dual-DLPC4420 chipsets. The DLPA300 micromirror driver creates VBIAS
and VOFFSET with internal voltage regulators. VRESET is created by an external regulator. These voltages are
switched by the DLPA300 micromirror driver on the OUT[0:14] pins which are connected to the MBRST pins on
the DMD.

reset waveforms created by the DLPA300 micromirror driver that are input to the MBRST pins on the DMD. This
results in the highest possible image quality and system efficiency.
The key design requirements are power supply sequencing for power up and power down. The 9-μm family of
DMDs require that the VCC2 supply be turned on after the 1.8-V supply is full on and stable. Similarly, on power
down, the DMDs require that the VCC2 supply be full off before the 1.8-V supply is begins its power off ramp.
The DLPA300 micromirror driver imparts one power supply sequencing constraint. Because VRESET is generated
by an external supply, the DLPC4430 display controller cannot control this supply directly by software. Therefore,
it is necessary to use the VBIAS supply to control the power up and power down of the external VRESET power
supply.
These power supply sequencing requirements necessitate external circuitry to control the VRESET and VCC2
power supply sequencing, as seen in 图8-1.
8.2.2 Detailed Design Procedure
The DLPC4430 or DLPC4420 display controller configures the VBIAS and VOFFSET voltage regulators in the
DLPA300 micromirror driver through the SCP bus. VBIAS is then used to generate the enable signal for the
VRESET external voltage regulator, LM43601 step-down voltage converter. When the VBIAS is enabled, it turns on
the two-transistor buffer amplifier. The 2N7002 and BSS84-7-F FETs isolate VBIAS from the VRESET_RAIL and shift
the voltage reference to VRESET_RAIL
.
The thermal pad on the DLPA300 micromirror controller and the LM43601 step-down voltage converter are
electrically connected to the VRESET_RAIL. Furthermore, the AGND and PGND pins on the LM43601 step-down
voltage converter are also connected to the VRESET_RAIL. Therefore, the logic levels and analog voltage levels for
LM43601 step-down voltage converter are referenced to the –16.5-V VRESET_RAIL
.
The LM43601 data sheet provides details for the component selection for the components in the voltage
regulator circuit connected to the VRESET_RAIL. The output of the regulator is set to the VRESET value of –16.5
V. The selection of the resistors in the resistor divider sets the output voltages, 6.49 kΩand 100 kΩ.
The DLP780NE power sequencing requires that the VCC2 power supply ramps up after the 1.8-V supply is
powered on and stable, and VOFFSET is powered up and stable. The two conditions are met by the wired-or of
the ERROR signal from the LP38513-1.8 ultra-low dropout linear regulator and an enable signal generated from
VOFFSET. The 2N7002 enhancement mode FET acts as an inverter and level shifter from VOFFSET to a 3.3-V logic
level.
In the event of a power supply failure (such as a pull-the-plug event), VCC2 must be driven low before the 1.8-V
supply starts to drop voltage. To achieve this, the TPS3847 12-V voltage monitor triggers a shunt-to-ground
power FET to pull VCC2 to ground.

8.2.3 Application Curves
The power supply sequencing for VBIAS, VOFFSET and VRESET are shown in 图 8-2 and 图 8-3. On power-up, the
turn on of VBIAS enables the external VRESET voltage regulator. In power-down, when VBIAS powers off, it
disables the VRESET regulator, which slowly decays to ground.
The power sequencing for VCC2 voltage regulator is shown in 图 8-4 and 图 8-5. The power up of VOFFSET
enables the turn on of the VCC2 voltage regulator. As seen in the zoom out of 图8-4, the 1.8-V supply is already
on and stable. Similarly, the power down of VOFFSET disables the VCC2 voltage regulator. The 1.8-V supply
powers down after both VOFFSET and VCC2 are powered down, as seen in the zoom out of 图8-5.

9 Power Supply Recommendations
9.1 Power Supply Rail Guidelines
表8-1 through 表8-4 provides discrete component selection guidelines.
• Ensure that the P12V filter and bypass capacitors are distributed and connected to pin 11 and pin 48 and pin
50. Place these capacitors as close to their respective pins as possible and if necessary, place on the bottom
layer.
• The V5REG filter and bypass capacitors must be placed near and connected to pin 47.
• It is best to route the VBIAS_RAIL etch runs in the following order: pin 40, pin 31, pin 30, pin 21, pin 80, pin
71, pin 70, and pin 61. Ensure that the etch runs are short and direct as they must carry 35 ns current spikes
of up to 0.64 A (peak). Locate the bypass capacitors near and connected to pin 30 and pin 71 to provide
bypassing on both sides.
• The VBIAS_LHI filter and bypass capacitors must be placed near and connected to pin 10.
• The VBIAS filter and bypass capacitors must be placed near and connected to pin 9.
• VBIAS pin 9 must also be connected (optionally with a 0-ohm resistor) to VBIAS_RAIL at or between pins 21
and 80.
• Route the VRESET_RAIL etch runs in the following order: pin 36, pin 35, pin 26, pin 25, pin 76, pin 75, pin
66, and pin 65. Ensure the etch runs are short and direct as they must carry 35 ns current spikes of up to
0.64 A (peak). Bypass capacitors must be placed near and connected to pins 35 and 66 to provide bypassing
on both sides.
• The VRESET filter and bypass capacitors must be located near and connected to pin 13. VRESET pin 13
must also be connected (optionally with a 0-Ωresistor) to VRESET_RAIL at or between pin 25 and pin 76.
• Route the VOFFSET_RAIL etch runs in the following order: pin 23, pin 28, pin 33, pin 38, pin 63, pin 68, pin
73, and pin 78. Ensure the etch runs are short and direct as they must carry 35 ns current spikes of up to
0.64 A (peak). Place the bypass capacitors near and connected to pin 28 and pin 73 to provide bypassing on
both sides.
• The VOFFSET filter and bypass capacitors must be placed near and connected to pin 49.
• VOFFSET pin 49 must also be connected (optionally with a 0-Ωresistor) to VOFFSET_RAIL at or between
pin 38 and pin 63.
备注
Aluminum electrolytic capacitors may not be suitable for the DLPA300 application. At the switching
frequencies used in the DLPA300 (up to 1.5 MHz), aluminum electrolytic capacitors drop significantly
in capacitance and increase in ESR resulting in voltage spikes on the power supply rails, which could
cause the device to shut down or perform in an unreliable manner.

Provide suitable Kelvin connections for the switching regulator feedback pins: VBIAS (pin 9) and VRESET (pin 13).
Make the PCB traces that connect the switching devices: VBIAS_SWL (pin 8) and VRESET_SWL (pin 12) as
short and wide as possible to minimize leakage inductances. Make the PCB traces that connect the switching
converter components (inductors, flywheel diodes and filtering capacitors) as short and wide as possible. Ensure
that the electrical loops that these components form are as small and compact as possible, with the ground
referenced components forming a star connection.
Due to the fast switching transitions appearing on the sixteen reset OUTx pins, it is recommended to keep these
traces as short as possible. Also, to minimize potential cross-talk between outputs, it is advisable to maintain as
much clearance between each of the output traces.
10.1.1 Grounding Guidelines
Ensure that the PWB has an internal ground plane that extends under the DLPA300. All nine ground pins (1, 7,
14, 20, 41, 46, 53, 55, and 60) must be connected to the ground plane using the shortest possible runs and vias.
All filter and bypass capacitors must be placed near the pin being filtered or bypassed for the shortest possible
runs to the part and to the ground plane.
10.2 Thermal Considerations
Thermally bond or solder the DLPA300 package to an external thermal pad on the PWB surface. The
recommended dimensions of the thermal pad are 10 mm × 10 mm centered under the device. The metal bottom
of the package is tied internally to the substrate at the VRESET_RAIL voltage level. Therefore, the thermal pad
on the board must be isolated from any other extraneous circuit or ground and no circuit vias are allowed inside
the pad area. Thermal pads are required on both sides of the PWB. Connect the thermal pads together through
an array of 5 × 5 thermal vias, 0.5 mm in diameter.
Thermal pads and the thermal vias are connected to VRESET_RAIL and must be isolated from ground,
or any other circuit.
Locate an internal P12V plane directly underneath the top layer and have an isolated area under the DLPA300.
This isolated area must be a minimum of 20 cm2 and connect to the thermal pad of the DLPA300 through the
thermal vias. The potential of the isolated area is also at VRESET_RAIL. The internal ground plane must extend
under the DLPA300 to help carry the heat away. Please refer to the PowerPAD Thermally Enhanced Package
application report (SLMA002) for details on thermally efficient package design considerations.
Be careful to place the DLPA300 device away from local PWB hotspots. Heat generated from adjacent
components may impact the DLPA300 thermal characteristics.
