BD9123MUV Description
BD9123MUV is ROHM’s high efficiency step-down switching regulator designed to produce voltage as low as 0.85V to 1.2V from a supply voltage of 5V/3.3V. It offers high efficiency by using pulse skip control technology and synchronous switches, and provides fast transient response to sudden load changes by implementing current mode control.
