NON-ISOLATED DC/DC CONVERTERS POWER PRODUCTS 3.3V Input / 5V Output / 4A BP02V7PC-04C V7PC-04C 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 * Industrial temperature range Description The Bel V7PC-04C series modules are non-isolated, boost DC/DC power converters that operate from a nominal 3.3V source. These converters provide an output voltage of 5V and are packaged in an industry standard single-in-line footprint with 4A maximum output. Standard features include remote on/off, over current and short circuit protection. A version of this converter is also available without remote on/off. These products may be used almost anywhere 5V is required and a 3.3V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment.
