Rohm BD95513MUV 3A开关电源方案

Rohm BD95513MUV 3A开关电源方案

　　BD95513MUV is a switching regulator capable of supplying high current output (up to 3A) 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 ROHMs proprietary H3RegTM control mode technology, yielding the industrys 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.
