NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 3.3V Input / 1.5 – 2.5V Output / 10A BP02V7PC-10C V7PC-10C 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 Description The Bel V7PC-10C series modules are non-isolated, DC/DC power converters that operate from a nominal 3.3V source. These converters are available in a range of output voltages from 1.5V to 2.5V. They are packaged in an industry standard single-in-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 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
