Delphi Series IPM24S0C0, Non-Isolated,
Integrated Point-of-Load Power Modules:
20V~36V input, 8.0~15.0V and 3A Output
The Delphi Series IPM24S0C0 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 3A of
output current or 45W 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.
IPM24S0C0 operates from a 20V~36V source and provides a
programmable output voltage from 8.0V to 15.0V. The IPM product
family is available in either a SMD or SIP package. IPM24S family is
also available for output 1.2V~2.5V or 3.3V~6.5V. Please refer to
IPM24S0A0 and IPM24S0B0 datasheets for details.

Note: Input reflected-ripple current is measured with a

Figure 15: Input reflected-ripple current test setup
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 26 shows the input ripple voltage
(mVp-p) for various output models using 2x100uF low
ESR electrolytic capacitors (Rubycon P/N:50YXG100,
100uF/50V or equivalent) and 1x3.3.0 uF very low ESR

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.

DESIGN CONSIDERATIONS
FEATURES DESCRIPTIONS
Remote On/Off
Over-Current Protection
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.
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.
The remote on/off pin is internally connected to +5Vdc
through an internal pull-up resistor. Figure 27 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.
Output Voltage Programming
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.

Q1
The output voltage shall be externally adjustable by use
of a Trim pin. The module output shall be adjusted by
either a voltage source referenced to ground or an
external resistor be connected between trim pin and Vo or
ground. To trim-down using an external resistor, connect
a resistor between the Trim and Vo pin of the module. To
trim up using an external resistor, connect the resistor
between the Trim and ground pins of the module. The
value of resistor is defined below. The module outputs
shall not be adversely affected (regulation and operation)
when the Trim pin is left open.
IPM can also be programmed by applying a voltage
between the TRIM and GND pins (Figure 20). The
following equation can be used to determine the value of
Vtrim needed for a desired output voltage Vo:

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).

Output voltage margining can be implemented in the IPM
modules by connecting a resistor, Rmargin-up, from the Trim
pin to the ground pin for margining-up the output voltage
and by connecting a resistor, Rmargin-down, from the Trim pin
to the output pin for margining-down. Figure 32 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
characterization setup. The power module is mounted on
a test PWB and is vertically positioned within the wind
tunnel. The height of this fan duct is constantly kept at
25.4mm (1’’).

* The allowed maximum hot spot temperature is defined at 125℃.

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.
