JAJSMY4 September 2021 UCC14240-Q1
The UCC14240-Q1 module uses an active full-bridge inverter on the primary-side and a passive full-bridge rectifier on the secondary-side. The small integrated transformer has a relatively high carrier frequency to reduce the size for integrating into the 36-pin SOIC package. The power stage carrier frequency operates within 10 MHz to 16 MHz. Spread spectrum modulation, SSM, is used to reduce emissions. ZVS operation is maintained to reduce switching power losses.
