BD95601MUV-LB
4.5V to 25V Input, 1ch Synchronous Buck DC/DC Controller
BD95601MUV-LB is a high current buck regulator that produces low output voltage (0.75V to 2.0V) from a wide input voltage range (4.5V to 25V). High efficiency is realized using external N channel MOSFETs. UsingH3RegTM, Rohm’s advanced proprietary control method that uses constant on-time control to provide ultra high transient responses to load changes. SLLM(Simple Light Load Mode) technology is added to improve efficiency with light loads giving high efficiency over a wide load range. Softstart functionality, short circuit protection with timer latch and over current protection are all included features. This switching regulator was designed for low voltage high current power supplies.
