NON-ISOLATED DC/DC CONVERTERS 10.8 Vdc - 13.2 Vdc Input VRPG-22A1AE 1.23 Vdc - 3.3 Vdc/21.5 A Output RoHS Compliant Rev.A • Non-Isolated • Under-Voltage Lockout (UVLO) • High Efficiency • OCP/SCP • Fixed Frequency • Output Voltage Trim • Low Cost • Power Good • UL60950-1 Recognized (UL/cUL) • Remote On/Off Description The Bel VRPG-22A1AE is part of the low cost non-isolated dc/dc converter power module series. The module use a SIP package for ease of layout and space savings. The output is closely regulated and can be trimmed from 1.23 Vdc to 3.3 Vdc over a wide range of input voltage (Vin=10.8 Vdc-13.2 Vdc). The efficiency is typically 79% at 1.23 Vdc output at full load. Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection.
