Datasheet 6V to 20V, 1A 1ch PWM Buck Converter Integrated FET BD9227F 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 compensation simplifies the external compensation calculation and reduces component 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. Key Specifications  Input Voltage Range: 6V to 20 V  Ref. Precision: PWM=H: ±2.0 %(±1.0 %@Ta=25°C)  Max Output Current: 1A (Max.)  Switching Frequency: 1.0MHz (Typ.
