7 / 11 page DC to DC Synchronous Converter Design Abdus Sattar, IXYS Corporation IXAN0068 7 Design Example 1: Assume design parameters as VIN=12V, VO=3.3V and Io=12A. Table 1: Design Consideration 1 for synchronous buck converter Input Voltage, Vin 12V Output Voltage, Vo 3.3V Output Current, Io 12A Assume the output ripple voltage is within ± 1% of Vo. For Vo =3.3V, the output ripple is limited within, V t V L 033 . 0 ) ( ≤ Δ . When the output capacitor (C1) is 10uF, the inductor L1 values for the range of switching frequencies from 100 kHz to 500 kHz are given in Table: 2 based on equations 3-7.
