The S24SE/S24DE series is miniature, isolated 15W DC/DC converters with 1600VDC isolation. The S24SE/S24DE family comes with
a host of industry-standard features, such as over current protection, over voltage protection, over temperature protection and remote on/off.
An optional heatsink is available for more extreme thermal requirements . All models have an untra-wide 4:1 input voltage range (9V to 36V).
With operating temperature of -40°C to +85°C, it is suitable for customers’ critical applications, such as process control and automation,
transportation, data communication and telecom equipment, test equipment, medical device and everywhere where space on the PCB is
critical.

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 47μF electrolytic capacitor
mounted close to the input of the module to improve the
stability.
Input Reflected Ripple Current

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

DESIGN CONSIDERATIONS
FEATURES DESCRIPTIONS
Layout and EMI considerations
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
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).

The remote on/off feature on the module can be
either negative or positive logic. Negative logic turns
the module on during a logic low and off during a
logic high. Positive logic turns the modules on during
a logic high and off during a logic low.
Test Result:
At T = +25C , Typical input voltage and full load.
Green is quasi peak mode; Blue is average mode.
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. For negative logic if the remote on/off
feature is not used, please short the on/off pin to Vi
(-). For positive logic if the remote on/off feature is
not used, please leave the on/off pin to floating.
Recommended PCB Layout
It is suggested to use multiple layers PCB and large size
copper on system board which connect to pins of module,
that can achieve better thermal performance.

For 12V signle output(Kohm):
Remote on/off implementation
For 15V single output(Kohm):
Output Voltage Adjustment(TRIM)
Only single output modules has 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 maximumu adjust range is ±10%, the TRIM pin
should be left open if this feature is not used.
For 3.3V single output(Kohm):
For example:
When need trim up to 3.4V, then the external resistor
should be 100Kohm between trim pin and Vout- pin.
When need trim down to 3.1V, then the external resistor
should be 40Kohm between trim pin and Vout+ pin.
THERMAL CONSIDERATIONS
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.
For 5V single output(Kohm):
Air velocity and ambient
temperature test point.
