Designing a High-Efficiency Boost Converter for 18V Output Voltage

[esso]

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 ampi 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

Hey, just curious but did your design work?
