A low ac-impedance input source is recommended. If the source inductance is m ore 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 Vin+ Vin- is ic 100uF, ESR=0.2 ohm @ 25oC 100KHz Cs: 220uF + + Vin+ Vin- is ic 100uF, ESR=0.2 ohm @ 25oC 100KHz Cs: 220uF + + is ic 100uF, ESR=0.2 ohm @ 25oC 100KHz Cs: 220uF ++ ++ Test set-up diagram showing measurement points for Input Terminal Rip ple Current and Input Reflected Ripple Current.

Input Terminal Ripple Current, ic, at full rated output current and nominal input voltage w ith 12µH source impedance and 100µF electrolytic capacitor ( 25 mA/div, 2us/div). Input reflected ripple current, is, through a 12µH source inductor at nominal input vo ltage and rated load current (5 mA/div, 2us/div) Output Ripple Noise Output voltage ripple test setup. Load capacitance: 1µF ceramic capacitor and 10µF tantalum capacitor. Bandwidth: 20 MHz. Scope measurements should be made using a BNC cable (length shorter than 20 inches). Position the load between 51 mm to 76 mm (2 inches to 3 inches) from the module.

For design assistance with EMC compliance and related P WB 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). L1=1uH C1=47uF/50V, electrolytic capacitor

Green is quasi peak mode; Blue is average mode. 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. FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over -current protection circuit, which will endure current limiting for an unlimited duration during ou tput 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 cont inue 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 mo dules will shut down, and then restart after a hiccup-time (hiccup mode). If latch mode is needed, please contact with Delta. Over-Temperature Protection 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. Remote On/Off 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. 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.
15W Single/Dual Output DC/DC Converter DS_S24SE/S24DE 15W _10172013 E-mail:DCDC@delta.com.tw http://www.deltaww.com/dcdc P9 For 12V signle output(Kohm): For 15V 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 powe r module’s case temperature should always be operated below 105 ℃. If the case temper ature exceeds the maximum operating temperature, reliability of the unit may be affected. AIR FLOW MODULE Air velocity and ambient temperature test point. 50.8mm (2.0")15.0mm (0.6") Remote on/off implementation Output Voltage Adjustment(TRIM) Only single output modules has output adjust function. To increase the output voltag e 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%, t he TRIM pin should be left open if this feature is not used. For 3.3V single output(Kohm): For 5V single output(Kohm):
