Product Description

The ML4824CP1 is a CCM PFC + PWM Combination Controller for switched mode power supplies. The Power Factor Correction (PFC) allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs and results in a power supply that fully complies with IEC1000-2-3 specification. The ML4824 includes circuits for the implementation of a leading edge, average current, boost type power factor correction and a trailing edge and pulse width modulator (PWM). The device is available in two versions of ML4824-1 (fPWM=fPFC) and ML4824-2 (fPWM=2 x fPFC). Doubling the switching frequency of the PWM allows the user to design with smaller output components while maintaining the best operating frequency for the PFC. An over-voltage comparator shuts down the PFC section in the event of a sudden decrease in load. The PFC section also includes peak current limiting and input voltage brown-out protection.
Internally synchronized PFC and PWM in one IC
Low total harmonic distortion
Reduces ripple current in the storage capacitor between the PFC and PWM sections
Average current, continuous boost leading edge PFC
Fast trans conductance error amp for voltage loop
High efficiency trailing edge PWM can be configured for current mode or voltage mode operation
Average line voltage compensation with brownout control
PFC overvoltage comparator eliminates output runaway due to load removal
Current fed gain modulator for improved noise immunity
Overvoltage protection, UVLO and soft start
