NON-ISOLATED DC/DC CONVERTERS 3.3 V Input 0.9 V-2.5 V/15 A Output V7PB-15C Series • Non-Isolated • Over Temperature Protection • High Efficiency • Under-voltage Lockout (UVLO) • High Power Density • OCP/SCP • Fixed Frequency (300 kHz) • Industrial Temperature Range • Low Cost • Remote Sense • Remote On/Off • Active Low/High (option) • Industry Standard Footprint Description The Bel V7PB-15Cxxx is part of the low cost non-isolated dc/dc converter series. The modules use a SIP package for ease of layout and space savings. The output is closely regulated and the efficiency is typically 93% at 2.5 V output at full load. Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection.
