NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 5V Input / 1.2V – 3.3V Output / 15A BP06VRPD-15B VRPD-15B Series RoHS Compliant • Nonisolated • Industry standard pinout • Fixed frequency • High efficiency means less power dissipation • Optimized for cost • Remote on/off • Undervoltage lockout (UVLO) • Over current and short circuit protection • Remote sense • Over temperature shutdown protection Description The Bel VRPD-15B 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 1.2V to 3.3V. They are packaged in an industry standard, single-in-line footprint and provide a maximum 15A output. Standard features include remote on/off, over current and short circuit protection, output voltage adjust and remote sense. 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. Applications Options • Distributed power architectures • • Data networking equipment • Telecommunications • Computers and peripherals Reverse remote on/off logic Part Number Selection Output Voltage Input Voltage Max.
