BD9227F Overview
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.
