Additional Infomation About Product

Datasheet 6V to 20V, 1A 1ch PWM Buck Converter Int egrated FET BD9227F General Description Key Specifications The BD9227F is a 20V, 1A non-synchronous PWM duty Input Voltage Range: 6V to 20 V control buck converter with integrated internal high-side Ref. Precision: PWM=H: 2.0 %(1.0 % Ta=25C) 20V Power MOSFET. Operating frequency is 1.0MHz Max Output Current: 1A (Max.) fixed by inner circuit. Current mode control with internal Switching Frequency: 1.0MHz (Typ.) slope compensation simplifies the external compensation Operating Temperature Range: -40 to +85C calculation and reduces component count while allowing the use of ceramic output capacitors. Additional Packages W(Typ) x D(Typ) x H(Max) protection features are included such as Over Current SOP8 5.00mm x 6.20mm x 1.71mm Protection, Thermal Shutdown and Under Voltage Lockout. The BD9227F is available in SOP8. Features Wide Operating Input Range 6V to 20V 20V/200m Internal Power MOSFET 1.0MHz Fixed Operating Frequency Current Mode SOP8 Over Current Hiccup Period Protection Applications Under Voltage Locked Out(UVLO), Over Voltage Home Appliance Protection(OVP), Thermal Shut Down(TSD) VM Motor Available in SOP8 Package.
