BD9227F
BD9227F is PWM Buck Converter manufactured by ROHM.
6V to 20V, 1A 1ch PWM Buck Converter Integrated FET
General Description The BD9227F is a 20V, 1A non-synchronous PWM duty control buck converter with integrated internal high-side 20V Power MOSFET. Operating frequency is 1.0MHz fixed by inner circuit. Current mode control with internal slope pensation simplifies the external pensation calculation and reduces ponent count while allowing the use of ceramic output capacitors. Additional protection Features are included such as Over Current Protection, Thermal Shutdown and Under Voltage Lockout. The BD9227F is available in SOP8.
