NON-ISOLATED DC/DC CONVERTERS 4.5V – 13.2V Input / 1.0V – 5.0V Output / 10A POWER PRODUCTS BP03S7DB-10E S7DB-10E Series • Nonisolated • Compact, low profile surface mount package • Wide input • High efficiency means less power dissipation • Excellent thermal performance • Optimized for cost • Remote on/off • Undervoltage lockout (UVLO) • Over current and short circuit protection • Remote sense • Active high/low Description The Bel S7DB-10E modules are a series of non-isolated, step down DC/DC power converters that operate from a nominal 4.5V to 13.2V source. These converters are available in a range of output voltages from 1.0V to 5.0V. The output is closely regulated and the efficiency of the 3.3V output module is typically 88% at full load. The modules are packaged in a compact, low profile, surface mount DIP package for ease of layout and space savings. 10A maximum output is also provided. Standard features include remote on/off, remote sense, over current and short circuit protection, UVLO and output voltage adjust. These products may be used almost anywhere low voltage silicon is employed and a 4.5V to 13.2V source is available. Typical applications include file servers, routers, line cards and other computing and communications equipment. Applications • Distributed power architectures • Data networking equipment • Telecommunications • Computers and peripherals Part Number Selection Output Voltage Input Voltage Max. Output Current Max.
