High-Performance Regulators for PCs

Switching Regulator with MOS FET

for DDR-SDRAM Cores

BD95513MUV

●

Description

BD95513MUV is a switching regulator capable of supplying high current output (up to 3A) at low output voltages (0.7V~5.0V)

over a broad range of input voltages (4.5V~28V). The regulator features an internal N-MOSFET power transistor for high

efficiency and low space consumption, while incorporating ROHM’s proprietary H

the industry’s fastest transient response time against load changes. SLLM

integrated to improve efficiency when powering lighter loads, as well as soft start, variable frequency, short-circuit protection

with timer latch, over-voltage protection, and REF functions. This regulator is suited for PC applications.
