NON-ISOLATED DC/DC CONVERTERS 12V Input / 1.5V – 5.0V Output / 3A S7AH-03A / V7AH-03A Series • • • • • • • • • Nonisolated Compact, low profile surface mount package Fixed frequency High efficiency means less power dissipation Excellent thermal performance Optimized for cost Remote on/off Undervoltage lockout (UVLO) Over current and short circuit protection POWER PRODUCTS BP02x7AH-03A Description The Bel S7AH-03A and V7AH-03A modules are a series of 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 5.0V. They are packaged in a compact, overmolded package rated at 3A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. Standard features include remote on/off, over current and short circuit protection, and output voltage adjust. 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.
