NON-ISOLATED DC/DC CONVERTERS 3.3 V Input 5.0 V / 4 A Output xRPC-04C50x RoHS Compliant • Non-Isolated • Low Cost • High Efficiency • High Power Density • Fixed Frequency • Industry Standard Footprint Description The xRPC-04C50x series are part of low-cost non-isolated boost dc/dc converters that operate from a nominal 3.3 V source. The modules use a SIP package for ease of layout and space savings. The output is closely regulated and the efficiency for 5.0 V output is typically 92.5% at full load. Standard features include high efficiency, fixed frequency, industry standard footprint and high power density. Part Selection Output Voltage 5.0 V Input Voltage 3.3 V Max. Output Current 4A Max. Output Power 20 W Typical Efficiency 92.5% Model Number Without Coating VRPC-04C50A Model Number With Coating 1 VRPC-04C50W Notes: 1. “W” indicates special coating. 2. Replace the first letter of the model number with "0" for horizontal mount package. 3. Add “G” suffix at the end of the model numbers listed above to indicate “Tray Packaging”. Absolute Maximum Ratings Parameter Input Voltage (continuous) Min -0.3 V Typ - Max 5V Ambient Temperature -40 °C - 85 °C Storage Temperature -40 °C - 125 °C Notes Note: Use beyond the maximum ratings may cause a reliability degradation of the dc/dc converter or may permanently damage the device.
