Datasheet 2.7V to 5.5V, 1.2A 1ch Synchronous Buck Converter with Integrated FET BD9123MUV General 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. Features ■ Fast Transient Response with Current Mode PWM Control System. ■ High Efficiency for All Load Range with Synchronous Rectifier (Nch/Pch FET) and SLLMTM (Simple Light Load Mode) ■ Output Voltage Selector (3 bit) ■ PGOOD Function ■ Soft-Start Function ■ Thermal Shutdown and UVLO Functions.
