Nonisolated Compact, profile surface mount package Fixed frequency High efficiency means less power dissipation Excellent thermal performance Optimized cost Remote on/off Undervoltage lockout (UVLO) Over current short circuit protection Remote sense
BP06SRDB-07A
RoHS Compliant
Description
SRDB-07A modules series non-isolated, step down DC/DC power converters that operate from nominal source. These converters available range output voltages from 1.2V 5.0V. They packaged compact, profile, surface mount package ease layout space savings. maximum output also provided. Standard features include remote on/off, over current short circuit protection, UVLO output voltage adjust. These products used almost anywhere voltage silicon employed source available. Typical applications include file servers, routers, line cards other computing communications equipment.
