NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 5V Input / 1.5 – 3.3V Output / 6A BP06VRPB-06B VRPB-06B Series RoHS Compliant • Nonisolated • Industry standard pinout with shorter package length • Fixed frequency • High efficiency • Excellent thermal performance • Low cost • Remote on/off • Undervoltage lockout • Over current and short circuit protection Description The Bel VRPB-06B series modules are 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 1.5V to 3.3V. They are packaged in an industry standard single-in-line footprint and provide a maximum 6A output. Standard features include remote on/off, over current protection and output voltage adjust. Optional features include remote sense and industrial temperature range. 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 • Telecommunications • Remote sense • Networking • Industrial temperature range • Computers and peripherals Part Number Selection Output Voltage Input Voltage Max.
