BD9G101G Simple Step-Down Switching Regulator (42Vin, 500mA)


Simple step-down switching regulator with built-in power MOSFET from ROHM

The BD9G101G is a non-synchronous step down switching regulator. An integrated internal high-side 42 V Power MOSFET provides up to 500mA of DC output current in a tiny SOT23-6 (SSOP6) package. In addition to a small package, a fixed 1.5 MHz operating frequency allows the use of small inductors and ceramic capacitors. No external compensation is required and an evaluation kit is also available for testing.
