High efficiency, high power factor and reliable power supply are the main focus of the PMP9531 design for motor driver applications. Transition mode (TM) power factor correction (PFC) with UCC28051 and LLC series resonant converter (SRC) with UCC25600 are applied in PMP9531. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. 93% converter efficiency is achieved at high line while still obtaining 90% converter efficiency at low line.
