Product Summary
The ML4824CS-1 is a controller for power factor corrected, switched mode power supplies. The ML4824CS-1 includes circuits for the implementation of a leading edge, average current, boost type power factor correction and a trailing edge, pulse width modulator (PWM). The ML4824CS-1 is available in two versions; the ML4824-1 (fPWM = fPFC) and the ML4824-2 (fPWM = 2 x fPFC) .
Parametrics
ML4824CS-1 absolute maximum ratings: (1) VCC Shunt Regulator Current: 55mA; (2) ISENSE Voltage: -3V to 5V; (3) Voltage on Any Other Pin: GND – 0.3V to VCCZ + 0.3V; (4) IREF: 20mA; (5) IAC Input Current: 10mA; (6) Peak PFC OUT Current, Source or Sink: 500mA; (7) Peak PWM OUT Current, Source or Sink: 500mA; (8) Junction Temperature: 150°C ; (9) Storage Temperature Range: -65°C to 150 °C ; (10) Lead Temperature (Soldering, 10 sec) : 260°C; (11) Temperature Range: -40°C to 85°C .
Features
ML4824CS-1 features: (1) Internally synchronized PFC and PWM in one IC; (2) Low total harmonic distortion; (3) Reduces ripple current in the storage capacitor between the PFC and PWM sections; (4) igh efficiency trailing edge PWM can be configured for current mode or voltage mode operation; (5) Average line voltage compensation with brownout control; (6) Current fed gain modulator for improved noise immunity; (7) Average current, continuous boost leading edge PFC; (8) Overvoltage protection, UVLO, and soft start.
