NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 5V Input / 1.2V – 3.3V Output / 5A BP06xRAH-05B SRAH-05B / VRAH-05B Series RoHS Compliant • Nonisolated • Compact, low profile surface mount package • Fixed frequency • High efficiency means less power dissipation • Excellent thermal performance • Optimized for cost • Remote on/off • Undervoltage lockout (UVLO) • Over current and short circuit protection Description The Bel SRAH-05B and VRAH-05B 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 a compact, overmolded package rated at 5A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. Standard features include remote on/off, over current and short circuit protection, and output voltage adjust. 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 • Distributed power architectures • Data networking equipment • Telecommunications • Computers and peripherals Part Number Selection Output Voltage Input Voltage Max. Output Current Max.
