| NON-ISOLATED DC/DC CONVERTERS 5V Input / 0.9V - 3.3V Output / 10A V7PB-10B Series * * * * * * * * * * * Nonisolated Industry standard footprint Fixed frequency High efficiency means less power dissipation Excellent thermal performance Optimized for cost Remote on/off Remote sense Undervoltage lockout (UVLO) Over current and short circuit protection Industrial temperature range POWER PRODUCTS BP03V7PB-10B Description The Bel V7PB-10B modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 5V source. These converters are available in a range of output voltages from 0.9V to 3.3V. They are packaged in a compact, SIP package rated at 10A. Standard features include remote on/off, over current and short circuit protection, output voltage adjust and industrial temperature range (-40 to +85 C). The output is closely regulated and the efficiency is typically 95.5% @ 3.3V output at full load. These products may be used almost anywhere low voltage silicon is employed and a 5V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
