DS_S24SP_40W_01212016 E-mail: [email protected] http://www.deltaww.com/dcdc P7 S24SP series 40W Single 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 100μF electrolytic capacitor mounted close to the input of the module to improve the stability. Input Reflected Ripple Current is ic Vin+ + + Vin- Cs: 220uF Input reflected ripple current, is, through a 12µH source inductor at nominal input voltage and rated load current (25 mA/div, 4us/div) 100uF, ESR=0.2 ohm @ 25oC 100KHz Output Ripple Noise Test set-up diagram showing measurement points for Input Terminal Ripple Current and Input Reflected Ripple Current.

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. Input Terminal Ripple Current, ic, at full rated output current and nominal input voltage with 12µH source impedance and 100µF electrolytic capacitor (250 mA/div, 4us/div).

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. DS_S24SP_40W_01212016 E-mail: [email protected] http://www.deltaww.com/dcdc P9 S24SP series 40W Single Output DC/DC Converter 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.
