4.5-28V 4A 1ch Synchronous Buck converter with Built-in Linear Regulator - BD95514MUV

BD95514MUV is a switching regulator capable of supplying high current output (up to 4A) at low output voltages (0.7V to 5.0V) over a broad range of input voltages (4.5V to 28V). The regulator features an internal N-MOSFET power transistor for high efficiency and low space consumption, while incorporating ROHM's proprietary H3Reg™ control mode technology, yielding the industry's fastest transient response time against load changes. SLLM (Simple Light Load Mode) technology is also 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.
