Datasheet

3.0 V to 36 V Input, 2.0 A Integrated FET

Single Synchronous Quiescent Operating

Current Buck DC/DC Converter for Automotive

BD9P233MUF-C

General Description

Key Specifications

BD9P233MUF-C is an ultra-low I_QBuck converter for 3.3

V output. The LLM (Light Load Mode) control ensures an

ultra-low quiescent current and high efficiency at light

load situation as well as at high load situations while

maintaining a regulated output voltage.
