onsemi PFC/PWM Controller Combination

onsemi highly integrated PFC/PWM Controller Combination ICs are specifically designed for power supplies that consist of a boost PFC and PWM. These PFC/PWM Controller Combination ICs require very few external components to achieve protection/compensation.

onsemi PFC/PWM Controller Combination ICs can be used in either current or voltage mode. In voltage mode, feed-forward from the PFC output bus can reduce the secondary output ripple. These PFC/PWM Controller Combination ICs offer features that include low operating current, innovative switching-charge multiplier divider, an average-current mode for input-current shaping, PFC over-voltage and under-voltage protection, PFC feedback open-loop protection, power-on sequence control, and soft start and brownout protection.

Features

  • Pin-to-Pin compatible with ML4800, FAN4800, CM6800 and CM6800A
  • PWM configurable for Current-Mode or feed-forward Voltage-Mode operation
  • Internally synchronized leading-edge PFC and trailing-edge PWM in one IC
  • Low operating current
  • Innovative switching-charge multiplier divider
  • Average-Current mode for Input-Current shaping
  • PFC Over-Voltage and Under-Voltage protections
  • PFC feedback open-loop protection
  • Cycle-by-cycle current limiting for PFC/PWM
  • Power-on sequence control and soft start
  • Brownout protection
  • Interleaved PFC/PWM switching
  • Improved efficiency at light load
