Centauri II (APC12) Non-Isolated DC/DC Power Module

Tiny SMT Footprint – 1.8V-12V Input, 0.9V to 3.6V Output

_{The APC12 Centauri II series is Astec’}P_sR_reE_ceL_ntIM_adI_dN_itiA_onR_tY_{o its non-isolated SMT POL line. With the wide}

acceptance of it’s predecessor (APC08 series) and the continuous system requirement for higher load current, the

Centauri platform have been revolutionized to provide 12A load current from it’s original 8A device. The APC12

offers the same standard features common to the Centauri Product Line: wide input voltage range; wide output

voltage range; high efficiency; Positive Output Enable; Power Good signal and Current Sharing. It also adapts the

same Centauri SMT footprint for optimum user flexibility and multiple sourcing.

The APC12 also comes with an output Trim pin, which allows output adjustment from 0.9V to 3.6V through

external resistance programming. It works from a wide input voltage range of 1.8V to 13V and offers an extensive

array of output voltages starting from 0.9V to 3.6V. It is ideal for Point of Load applications and provides the most

flexibility for the ever-changing DSP and ASIC power requirements.

Basic Operation and Features

The APC08/12 Centauri family was designed specifically to address applications where on board distributed power with Point-

of-Load Converters (Conversion needed as close to the IC, usually DSP’s and ASIC’s) is employed. With its wide range input

and flexible programmable output, any change in the load becomes very manageable with little to no impact on time to market.

All of the converters in this family are buck converters. The APC12x03 versions allow 1.8V to 6V input voltage and the

APC12x08 versions allow a 5.6V to 13V input with 14V max surge.

MODULE PIN ASSIGNMENT

There are 4 to 7 surface mount pins on a Centauri module. The availability of pins from individual modules is relevant

to its version / selected option.

When ordered with no options, the module comes with only 4 pins – V_IN, Gnd, V_OUTand Enable – AND IS

COMPATIBLE WITH OTHER LEADING MANUFACTURER’s FOOTPRINT. When the full-featured module is

required: with Output Trim; Active Current Share and Power Good Signal PINs, “-9MA” suffix is added to the

standard part number. Please refer to the Part Number Ordering Scheme for other options (including packaging).

Note: When using the trim function, this module offers much more trim flexibility than the competitive footprint and also

requires a jumper between the two footprints to be source compatible. Contact Factory for details.

Enable Pin (Standard configuration)

Pin P5 is functioned to enable the output voltage of a

module. If this pin is left open or connected to ≥ 4.1Vdc

up to 14Vdc, the module is turned on. On the other hand,

if this pin is connected to ground or to a voltage potential

from 0 to 0.8Vdc, the module is turned off. The enable pin

can source current up to 60µA max - suited for typical

open-collector transistors readily available in the market.

For TTL compatibility, Figure 3 shows a 7405 open

collector inverter IC utilized to function the Enable

feature. Other common chips that can do the function are

74S05; 74HCT05; non-inverting - 7407; 74S07; 74HC07.

If SMT packaging is preferred, Fairchild's Tiny Logic

NC7SZ05 or TI's Little Logic SN7SLVC1G06 comes in SOT23

or SC70 packages.

Special Feature Pins (Options):

Trim Function (-9):

Pin P4 is used for output voltage adjustment. The output voltage can be trimmed through an external resistor or through an

external DC supply as described in the succeeding sections.

Method 1: External Trim Resistor.

By connecting an external resistor across P4 and P3 (Gnd), the voltage appearing on pin P2 (Vo) is adjusted to a higher value.

The output voltage of a module can be adjusted up to a maximum value of 3.3V (nominal) or 83% of the input voltage,

whichever is lower. By connecting an external resistor across P4 and P2, Vo is adjusted to a lower value. Only small

reductions, 2%, in voltage are recommended, as adjustment to lower voltages tends to affect the loop compensation of the

module.

Full range adjustment (from 0.9V to 3.6V) can be obtained from a module with the lowest Vo setpoint (0.9Vo).

To adjust Vo to a higher value, please refer to

Figure 4. The required resistor value (Rt) can be

determined through Equation (1) where Vo is the

voltage on P2 before the adjustment and Vot is the

voltage of P2 after Rt is connected.

Requiring to adjust output voltage from Vo = 0.9V to Vot = 1.8V. V_ref= 0.87V and R₁= 3.09kΩ (from TABLE 1).

Based on Equation (1), Rt can be determined as 3.0kΩ.

To adjust Vo to a lower value, Rt should be connected between P4 and P2. Equation (2) provides the calculation for Rt.

Vo = 3.3V, Vot = 3.234V, V_ref= 0.87V, R₂= 1.13kΩ (from TABLE 1).

Based on Equation (1), Rt can be determined as 111.9kΩ.

Method 2: External DC Source

By connecting an external DC supply across P4 (Enable) and P3 (GND) through a limiting resistor Rt, (see Figure 5), output

voltage adjustment can also be achieved. Equation 3 provides the relationship between the External DC supply, Vt, and Vo

(where Vo is the desired output voltage).

Vo Adjustment to Lower Voltages. This method does not limit the recommended lower Vo adjustment to 2% as mentioned

on previous sections re: Vo adjustment through external trim resistor.

Example:

Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).

Requiring to adjust the output voltage from Vo = 2.5V to 1.8V

Vo = 1.8V, V_ref= 0.87V, R₁= 3.09kΩ, R₂= 1.69kΩ (from Table 1). Based on Equation (3), Vt = 3.0V.

Example:

Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).

Requiring to adjust the output voltage from Vo = 2.5V to 0.9V

Vo = 0.9V, V_ref= 0.87V, R₁= 3.09kΩ, R₂= 1.69kΩ (from Table 1). Based on Equation (3), Vt = 5.9V.

Vo Adjustment to Higher Voltages

Example:

Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).

Requiring to adjust the output voltage from Vo = 2.5V to 3.3V

Vo = 3.3V, V_ref= 0.87V, R₁= 3.09kΩ, R₂= 1.69kΩ (from Table 1). Based on Equation (3), Vt = -1.84V.

If application of negative voltage is not desired, the limiting resistor Rt can either be changed to a lower value (Rt = 1kΩ, such

that Vt = 0.60V per Equation 3), or use Method 1.

Power Good Signal Operation (Option (-9MA)):

PG pin provides an output signal indicating the Vout is

operational (TTL logic signal). It can sink current up to a max

of 5mA and can have a maximum external pull-up voltage of

6V. Please see recommended setup shown on Figure 6.

Figure 6. PGood setup.

Active Current Share Operation (Option (-9MA)):

Active Current share pin is compatible with like modules only (APC08 to APC08 or APC12 to APC12). Connecting this pin

directly with the same Pin from another module guarantees current sharing to within 40% to 60% Iout. Note that this pin is not

compatible with competitive modules that employ active current sharing.

To attain efficient current sharing between like modules, the following points are recommended:

a) The modules to be shared should be located as close as possible into the host card.

b) The copper tracks that connect Vo and GND should at least be 0.60" in width with at least 2 oz. Cu.

RECOMMENDED LOCATION FOR PICK AND PLACE

The flat top surface of the large inductor (topside of the board) provides a versatile and convenient way of picking up the

module (see Figure 56). A 6-7mm outside diameter nozzle from a conventional SMD machine is recommended to attain

maximum vacuum pick-up. Nozzle travel and rotation speed should be controlled to prevent this off-centered picked-up

module from falling off the nozzle. The use of vision recognition systems for placement accuracy will be very helpful.

PEAK TEMPERATURE

1. Refer to the recommended Reflow Profile per

Figure 57. Profile parameters exceeding the

recommended maximums may result to

permanent damage to the module.

2. The module is recommended for topside

reflow process to the host card. For other

orientations, contact factory.

3. In the event that the module needs to be

desoldered from the host card, some pins

may be detached from the module.

PACKING AND SHIPPING

Standard packaging for the modules will be in tape and reel. Jedec-style tray packaging is also available (add suffix

"J" in pn). Please refer to the ordering information. Maximum number of modules in a reel is 250 pcs. The tray can

hold 35 modules max. Please refer to Figure 59 for the T&R carrier dimensions and Figure 60 for the tray dimensions.
