9A Highly Integrated SupIRBuck Single-input Voltage, Synchronous Buck Regulator toolkit
This page will help to configure IR3899 and calculate component values for your application.
This calculator is suitable well also for most of other voltage-feedback power converters. Enter corrent voltage reference (TL431 = 2.5V, Lot of LDOs 1.25 or 0.8V), and resistance divider R5,R6 values to get output voltage.
