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.

Note: Input reflected-ripple current is measured with a

measured at the input of the module.
Figure 25: 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 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,

The power module should be connected to a low

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

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.
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.
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 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.

Vin
IPM
On/Off
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.
Output Voltage Programming
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:

For example: to program the output voltage of the IPM
module to 3.3Vdc, Rtrim is calculated as follows:

Figure 31:
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
Trim down Circuit configuration for programming
output voltage using an external resistor
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
Vtrim = 0.7439 – 0.0488 x 3.3

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
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’’).

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.
