Homework Help: Design a boost converter

  1. Apr 28, 2008 #1
    i'm supposed to design a boost converter with the following parameters:
    supply voltage = 9-15 v
    output voltage = 18 v
    output current = 0.1 - 2 amp
    voltage ripple = 5%
    efficiency = 80 - 98%

    i came up with the following: let f= 30 KHz
    min C=12.3 uF
    min L=375 uH
    average supply current = 4 amp


    i need to know if my calculations are right , and i also need a suggestion about what IC should i use to control the circuit.
    thank you for helping
