SMD or SIP package

The Delphi Series IPM12C non-isolated, fully integrated

Point-of-Load (POL) power modules, are the latest offerings from a

world leader in power systems technology and manufacturing --

Delta Electronics, Inc. This product family provides up to 4A of

output current or 20W of output power in an industry standard,

compact, IC-like, molded package. It is highly integrated and does

not require external components to provide the point-of-load

function. A copper pad on the back of the module, in close contact

with the internal heat dissipation components, provides excellent

thermal performance. The assembly process of the modules is fully

automated with no manual assembly involved. These converters

possess outstanding electrical and thermal performance, as well as

extremely high reliability under highly stressful operating conditions.

IPM12C operates from an 8V~14V source and provides a

programmable output voltage of 0.9V to 5V. The IPM product family

is available in both a SMD or SIP package.

TEST CONFIGURATIONS

DESIGN CONSIDERATIONS

TO OSCILLOSCOPE

Input Source Impedance

To maintain low-noise and ripple at the input voltage, it is

critical to use low ESR capacitors at the input to the

module. Figure 28 shows the input ripple voltage

(mVp-p) for various output models using 2x47 uF low

ESR tantalum capacitors (SANYO P/N:16TPB470M,

47uF/16V or equivalent) or 2x22 uF very low ESR

ceramic capacitors (TDK P/N:C3225X7S1C226MT,

22uF/16V or equivalent).

Note: Input reflected-ripple current is measured with a

The power module should be connected to a low

ac-impedance input source. Highly inductive source

impedances can affect the stability of the module. An

input capacitance must be placed close to the modules

input pins to filter ripple current and ensure module

stability in the presence of inductive traces that supply

the input voltage to the module.

CONTACT RESISTANCE

Note: All measurements are taken at the module

terminals to avoid measurement errors due to

contact resistance.

DESIGN CONSIDERATIONS

FEATURES DESCRIPTIONS

Safety Considerations

Over-Current Protection

For safety-agency approval the power module must be

installed in compliance with the spacing and separation

requirements of the end-use safety agency standards.

To provide protection in an output over load fault

condition, the unit is equipped with internal over-current

protection. When the over-current protection is

triggered, the unit enters hiccup mode. The units

operate normally once the fault condition is removed.

For the converter output to be considered meeting the

requirements of safety extra-low voltage (SELV), the

input must meet SELV requirements. The power module

has extra-low voltage (ELV) outputs when all inputs are

ELV.

Pre-Bias Startup Capability

The IPM would perform the monotonic startup into the

pre-bias loads; so as to avoid a system voltage drop

occur upon application. In complex digital systems an

external voltage can sometimes be presented at the

output of the module during power on. This voltage may

be feedback through a multi-supply logic component,

such as FPGA or ASIC. Another way might be via a

clamp diode as part of a power up sequencing

implementation.

The input to these units is to be provided with a

maximum 10A time-delay fuse in the ungrounded lead.

Remote On/Off

The IPM series power modules have an On/Off control

pin for output voltage remote On/Off operation. The

On/Off pin is an open collector/drain logic input signal

that is referenced to ground. When On/Off control pin is

not used, leave the pin unconnected.

Output Voltage Programming

The remote on/off pin is internally connected to +Vin

through an internal pull-up resistor. Figure 29 shows the

circuit configuration for applying the remote on/off pin.

The module will execute a soft start ON when the

transistor Q1 is in the off state.

The output voltage of IPM can be programmed to any

voltage between 0.8Vdc and 5Vdc by connecting one

resistor (shown as Rtrim in Figure 30, 31) between the

TRIM and GND pins of the module to trim up (0.9V ~ 5V)

and between the Trim and +Output to trim down (0.8V ~

0.9V). Without this external resistor, the output voltage of

the module is 0.9 Vdc. To calculate the value of the

resistor Rtrim for a particular output voltage Vo, please

use the following equation:

The typical rise for this remote on/off pin at the output

voltage of 2.5V and 5.0V are shown in Figure 17 and 18.

IPM can also be programmed by applying a voltage

between the TRIM and GND pins (Figure 32). The

following equation can be used to determine the value of

Vtrim needed for a desired output voltage Vo:

Vtrim = 0.7439 – 0.0488Vo

Vtrim is the external voltage in V

Vo is the desired output voltage

For example, to program the output voltage of a IPM

module to 3.3 Vdc, Vtrim is calculated as follows

Figure 32: Circuit configuration for programming output voltage

using external voltage source

Vtrim = 0.7439 – 0.0488 x 3.3

Vtrim = 0.5829V

Figure 30: Trim up Circuit configuration for programming

output voltage using an external resistor

DS_IPM12C0A0R04_08242006

FEATURE DESCRIPTIONS (CON.)

Table 1 provides Rtrim values required for some common

output voltages, while Table 2 provides value of external

voltage source, Vtrim, for the same common output

voltages. By using a 0.5% tolerance resistor, set point

tolerance of ±2% can be achieved as specified in the

electrical specification.

The amount of power delivered by the module is the

voltage at the output terminals multiplied by the output

current. When using the trim feature, the output voltage

of the module can be increased, which at the same

output current would increase the power output of the

module. Care should be taken to ensure that the

maximum output power of the module must not exceed

the maximum rated power (Vo.set x Io.max ≤ P max).

Voltage Margining

Output voltage margining can be implemented in the IPM

modules by connecting a resistor, R^margin-up, from the Trim

pin to the ground pin for margining-up the output voltage

and by connecting a resistor, R^margin-down, from the Trim pin

to the output pin for margining-down. Figure 33 shows

the circuit configuration for output voltage margining. If

unused, leave the trim pin unconnected.

THERMAL CONSIDERATIONS

THERMAL CURVES

Thermal management is an important part of the system

design. To ensure proper, reliable operation, sufficient

cooling of the power module is needed over the entire

temperature range of the module. Convection cooling is

usually the dominant mode of heat transfer.

Hence, the choice of equipment to characterize the

thermal performance of the power module is a wind

tunnel.

Thermal Testing Setup

Delta’s DC/DC power modules are characterized in

heated vertical wind tunnels that simulate the thermal

environments encountered in most electronics

equipment. This type of equipment commonly uses

vertically mounted circuit cards in cabinet racks in which

the power modules are mounted.

The following figure shows the wind tunnel

Heat can be removed by increasing airflow over the

module. To enhance system reliability, the power

module should always be operated below the maximum

operating temperature. If the temperature exceeds the

maximum module temperature, reliability of the unit may

be affected.
