We are designing a 20W SMPS which simply supplies 15V at 1A to an RF Phased array antenna circuit. (its for comms). Vin = 48V.
We were wondering if it is overly extravagant to do this as an Half-Bridge LLC converter? Its just that the SMPS will be very close to the Comms signal processors and other sensitive circuitry, so we wondered should we do an LLC converter instead of the usual Hard Switching Buck converter?
