Features Regulated Converter Description Sixteenth brick format : input voltage range.kv basic isolation Remote ON/OFF and trim pins UVLO, OTP, OVP, OCP and SCP Efficiency up to 9% The RPAS is a low cost W DC/DC converter in industry standard /th brick format (mm x mm) and pinning. The : input range covers V, V or V nominal input voltages and the output voltage options are.v, V or V with +%/-% trim. Output power is W from -V or W from -V. The efficiency is particularly high (-9%) to permit full load operation from - C up to + C ambient temperature with only free air convection and up to C with forced air cooling. The isolation voltage is.kvdc/ minute (basic insulation grade). Applications include demanding industrial power supplies, telecom and PoE circuits. Selection Guide Part nom.

The values for trim resistors shown in trim tables below are according to standard E9 values; therefore, the specified voltage may slightly vary; they also can be calculated with below shown equation.
