Description

General part information

BD9P233MUF-C Series

BD9P233MUF-C is an ultra-low IQ Buck converter for 3.3V 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.
