Design Requirements

Designing with the UCC14240-Q1 module is simple. First, choose single output or dual output. Determine the voltage for each output and then set the regulation through resistor dividers. The gate charge of the power device determines the amount of output decoupling capacitance needed at the gate driver input. Calculate the RLIM resistor value for regulating the (COM – VEE) voltage rail for a dual output. Finally, add the recommended input and output capacitors according to the procedure below.
