BD95514MUV is a switching regulator capable of supplying high current output (up to 4A) 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 H3RegTM 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 tracking functions. This regulator is suited for PC applications.
The BD95514MUV is a high‑performance switching regulator designed for PC and consumer electronics. It delivers up to 4 A output over a wide input range of 4.5 V to 28 V and incorporates ROHM’s H’Reg™ control for fast transient response and light‑load efficiency.
