NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 12V Input / 1.5 – 3.3V Output / 10A BP01V7PC-10A V7PC-10A Series • Nonisolated • Industry standard pinout • Fixed frequency • High efficiency means less power dissipation • Optimized for cost • Remote on/off • Undervoltage lockout • Over current and short circuit protection Description The Bel V7PC-10A series modules are non-isolated, step down DC/DC power converters that operate from a nominal 12V 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 10A output. Standard features include remote on/off, over current 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 12V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
