NON-ISOLATED DC/DC CONVERTERS 4.5 V - 13.2 V Input 0.9 V - 5.0 V/15 A Output VRPB-15E Series • RoHS Compliant • Non-Isolated Over Temperature Protection • High Efficiency • Under-voltage Lockout (UVLO) • High Power Density • OCP/SCP • Low Cost • Remote Sense • Excellent Thermal Performance • Industrial Temperature Range • Remote On/Off • Wide Input Voltage Range • Active Low/High (option) • Wide Output Trim Range Description The Bel VRPB-15Exxx series are part of the low cost non-isolated dc/dc power converter series. These modules use a SIP package for ease of layout and space savings. The output is closely regulated and the efficiency at 3.3 V output is typically 92% at full load. Typical features include remote on/off, under-voltage lockout, wide input voltage range, wide output trim range, over-current protection and short circuit protection.
