BD9227F Datasheet (ROHM) - PWM Buck Converter

BD9227F, PWM Buck Converter

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 compensation simplifies the external compensation calculation and reduces compo
