NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 3.3V Input / 1.2V – 2.5V Output / 15A BP02V7PD-15C V7PD-15C Series • Nonisolated • Industry standard pinout • Fixed frequency • High efficiency means less power dissipation • Optimized for cost • Remote on/off • Undervoltage lockout (UVLO) • Over current and short circuit protection • Remote sense • Over temperature shutdown protection Description The Bel V7PD-15C modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 3.3V source. These converters are available in a range of output voltages from 1.2V to 2.5V. They are packaged in an industry standard, single-in-line footprint and provide a maximum 15A output. Standard features include remote on/off, over current and short circuit protection, output voltage adjust and remote sense. 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.
