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

AI Thread Summary
The discussion focuses on designing a boost converter with a supply voltage range of 9-15V, aiming for an 18V output at 0.1-2A with a voltage ripple of 5% and efficiency between 80-98%. The user calculated a switching frequency of 30 kHz, a minimum capacitance of 12.3 µF, and a minimum inductance of 375 µH, while estimating an average supply current of 4A. They seek validation of these calculations and recommendations for an appropriate integrated circuit (IC) to control the converter. The conversation also includes a follow-up inquiry about the success of the design. Accurate calculations and component selection are crucial for achieving the desired performance in boost converter designs.

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
