V7PC-10B

NON-ISOLATED DC/DC CONVERTERS 5V Input / 1.5 – 3.3V Output / 10A V7PC-10B Series • • • • • • • • • Nonisolated Industry standard pinout Fixed frequency High efficiency means less power dissipation High power density Optimized for cost Remote on/off Undervoltage lockout Over current and short circuit protection POWER PRODUCTS BP02V7PC-10B Description The Bel V7PC-10B series modules are non-isolated 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 singlein-line footprint with 10A maximum output. Standard features include remote on/off, over current and short circuit protection and output voltage adjust. Remote sense is an optional feature. 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.
