S24SE/S24DE series 10W Single/Dual Output DC/DC Converter 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.

S24SE/S24DE series 10W Single/Dual Output DC/DC Converter DESIGN CONSIDERATIONS FEATURES DESCRIPTIONS Layout and EMI considerations Over-Current Protection Delta’s DC/DC power modules are designed to operate The modules include an internal output over-current in a wide variety of systems and applications. For design protection circuit, which will endure current limiting assistance with EMC compliance and related PWB for an unlimited duration during output overload. If layout issues, please contact Delta’s technical support the output current exceeds the OCP set point, the team. An external input filter module is available for modules will shut down (hiccup mode). easier EMC compliance design. Below is the reference design for an input filter to pass EN55022 (VDE0878) The modules will try to restart after shutdown. If the class A (both q. peak and average). 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 L1=1uH output terminals. If this voltage exceeds the C1=47uF/50V, electrolytic capacitor over-voltage set point, the modules will shut down, and then restart after a hiccup-time (hiccup mode). dBμV 80.0 If latch mode is needed, please contact with Delta. 70.0 Limits 55022MAV 5 5022MQP Over-Temperature Protection 60.0 50.0 The over-temperature protection consists of circuitry 40.0 Transducer that provides protection from thermal damage. If the 8130 temperature exceeds the over-temperature 30.0 Traces PK+ threshold the module will shut down.The module will AV 20.0 restart after the temperature is within specification. 10.0 Remote On/Off 0.0 150 kHz 1 MHz 10 MHz 30 MHz Test Result: The remote on/off feature on the module can be either negative or positive logic depend on the part At T = +25C, Typical input voltage and full load. number options on the last page. Green is quasi peak mode; Blue is average mode.  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 Recommended PCB Layout 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.

S24SE/S24DE series 10W Single/Dual Output DC/DC Converter For 12V single output (Kohm): For 15V single output (Kohm): Remote on/off implementation Output Voltage Adjustment (TRIM) 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(+). For example: The maximum adjust range is ±10%, the TRIM pin When need trim up to 3.4V, then the external resistor should be left open if this feature is not used. should be 100Kohm between trim pin and Vout- pin. When need trim down to 3.1V, then the external resistor For 3.3V single output(Kohm): should be 40Kohm between trim pin and Vout+ pin. THERMAL CONSIDERATIONS Thermal de-rating curve is a standard for customer to make thermal evaluation and make sure the module’s components are operated under allowed temperature. The module’s cooling condition is natural convection. In thermal de-rating curve, if we know the module’s input voltage and output power we can find the allowed maximum ambient temperature. The module’s case temperature is a reference to make thermal evaluation. If the case temperature For 5V single output (Kohm): exceed the allowed maximum value, the moldule may probably have thermal issue.
