NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 3.3V Input / 0.9V – 2.5V Output / 10A BP03V7PB-10C V7PB-10C 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 Description The Bel V7PB-10C modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 3.3V source. These converters are available in a range of output voltages from 0.9V to 2.5V. 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% @ 2.5V output at full load. These products may be used almost anywhere low voltage silicon is employed and a 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment. Applications • Distributed power architectures • Data networking equipment • Telecommunications • Computers and peripherals Part Number Selection Output Voltage Input Voltage Max. Output Current Max.
