BD9137MUV

Datasheet 2.7V to 5.5V, 4A 1ch Synchronous Buck Converter with Integrated FET BD9137MUV General Description BD9137MUV is ROHM’s high efficiency step-down switching regulator designed to produce a voltage as low as 0.8V from a supply voltage of 5.5V/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 because of Current Mode PWM Control System.  High Efficiency for All Load Ranges because of Synchronous Switches (Nch/Nch FET) and SLLMTM (Simple Light Load Mode)  Soft-Start Function  Thermal Shutdown and UVLO Functions  Short-Circuit Protection with Time Delay Function  Shutdown Function Applications Power Supply for LSI including DSP, Microcomputer and ASIC Typical Application Circuit Key Specifications  Input Voltage Range:  Output Voltage Range:  Output Current:  Switching Fre...
