Rohm's BD9A301MUV single synchronous DC-DC step-down switching regulator with built-in low on-resistance power MOSFET.
The device delivers up to 3A and its SLLM control has excellent efficiency characteristics at light loads. This makes the BD9A301MUV ideal for devices that require minimal standby power consumption. When a smaller inductance value is used, the oscillation frequency is higher, which is 1MHz. The company states that the current-mode controlled DC-DC converters have easy-to-set high-speed transient response and phase compensation.
Typical applications include industrial equipment, step-down power supplies for DSP, FPGA, microprocessor, etc., storage devices (HDD / SSD), printers, OA equipment, distributed power supplies and auxiliary power supplies.
