Power factor correction (PFC) is an important part of power management, and MC33232D is a high performance, highly integrated PFC device. It is suitable for AC/DC PFC charger application due to its high accuracy, low cost and low power loss.

The MC33232D device is an integrated controller for active power-factor-correction (PFC) applications. It provides an accurate 12-bit analog-to-digital converter (ADC) fan-speed control, PWM dimming functions, AC-line monitoring, and over current protection. The device also has an internally regulated supply voltage that may be used to perform voltage and power measurement.

The MC33232D device integrates PFC boost converter with a fixed frequency, current-mode control topology. The integrated over-voltage protection (OVP) and over-temperature protection (OTP) systems suppress the peak inductor current and protect the device against power supply overstress conditions. The integral control functions support both continuous-conduction and discontinuous-conduction mode operations.

The MC33232D device supports multiple DC output voltage configurations. The device supports a single output voltage with no load step-down, or dual output voltages with load-sharing, and includes peak-load capacitance and EMI filter components. The device includes an ADC for sampling the voltage and current of the output voltage and also supports two external temperature-sensor measurements. It also provides a LCD (liquid crystal display) interface that allows easy monitoring of operating conditions.

The MC33232D device has a built-in soft-start and current-limiting function. This function limits the start-up and running current of the system to protect against overload and/or overvoltage conditions. It also features a built-in programmable reference voltage that allows for fine-tuning of the switching waveform. The MC33232D also includes an integrated power-up detector for deep-cycle protection and bus-under-voltage lockout.

The MC33232D device provides a highly efficient power-factor-correction solution for AC/DC PFC chargers. The high level of integration, low cost and low energy loss, make the MC33232D an attractive solution for power-factor-correction systems.
