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

I would suggest double-checking your calculations and making sure they are accurate. It is always important to verify your results before proceeding with a design. Additionally, I would suggest researching and comparing different boost converter ICs to find one that best fits your design parameters and requirements. Some popular options for high-efficiency boost converters include the LT3757, LTC3780, and MAX668. It is also important to consider the features and capabilities of each IC, such as input voltage range, output current capability, and efficiency. Ultimately, the best IC for your design will depend on your specific needs and trade-offs.
