DESIGN CONSIDERATIONS
Input Source Impedance
The impedance of the input source connecting to the
DC/DC power modules will interact with the modules
and affect the stability. A low ac-impedance input source
is recommended. If the source inductance is more than
a few μH, we advise a 100μF electrolytic capacitor
mounted close to the input of the module to improve the
stability.

Load capacitance: 1µF ceramic capacitor and 10µF

measurements should be made using a BNC cable
(length shorter than 20 inches). Position the load

the module.

DESIGN CONSIDERATIONS

FEATURES DESCRIPTIONS
Over-Current Protection
Delta’s DC/DC power modules are designed to operate
in a wide variety of systems and applications. For design
assistance with EMC compliance and related PWB
layout issues, please contact Delta’s technical support
team. An external input filter module is available for
easier EMC compliance design. Below is the reference
design for an input filter to pass EN55022 (VDE0878)
class A (both q. peak and average).
The modules include an internal output over-current
protection circuit, which will endure current limiting
for an unlimited duration during output overload. If
the output current exceeds the OCP set point, the
modules will shut down (hiccup mode).
The modules will try to restart after shutdown. If the
overload condition still exists, the module will shut
down again. This restart trial will continue until the
overload condition is corrected.
Over-Voltage Protection
EMI filter circuit
Cin=100uF/50V;Nippon chemi-con,ESR 85 mohm
The modules include an internal output over-voltage
protection circuit, which monitors the voltage on the
output terminals. If this voltage exceeds the
over-voltage set point, the modules will shut down,
and then restart after a hiccup-time (hiccup mode).
If latch mode is needed, please contact with Delta.
L1=4.7uH;PCMC063T-4R7MN
C1=6.8uF/50V/1812/MLCC
Over-Temperature Protection
CY1=6.8nF/2KV/1210/MLCC
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
temperature
exceeds
the
over-temperature
threshold the module will shut down.The module will
restart after the temperature is within specification.

Recommended PCB Layout
For Negative logic version, turns the module on
during a external logic low and off during a logic
high. If the remote on/off feature is not used,
please short the on/off pin to Vi (-).
For Postive logic version, turns the modules on
during a external logic high and off during a logic
low. If the remote on/off feature is not used,
please leave the on/off pin to floating.
Remote on/off can be controlled by an external
switch between the on/off terminal and the Vi (-)
terminal. The switch can be an open collector or
open drain.
It is suggested to use multiple layers PCB and large
size copper on system board which connects to pins of
module, that can achieve better thermal performance.

For 15V signle output (Kohm):
Remote on/off implementation
Output Voltage Adjustment (TRIM)
For 24V single output (Kohm):
Only single output modules have output adjust
function.
To increase the output voltage set point, connect an
external resistor between the TRIM pin and the
Vout(-).
To decrease the output voltage set point, connect an
external resistor between the TRIM pin and the
Vout(+).
The maximum adjust range is ±10%, the TRIM pin
should be left open if this feature is not used.
For 5V single output (Kohm):
For example:
When need trim up to 5.2V, then the external resistor
should be 95.2Kohm between trim pin and Vout- pin.
When need trim down to 4.9V, then the external resistor
should be 291.2Kohm between trim pin and Vout+ pin.
THERMAL CONSIDERATIONS
For 12V single output (Kohm):
Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module’s case temperature should always be operated
below 105℃. If the case temperature exceeds the
maximum operating temperature, reliability of the unit
may be affected.
