Variable Feedforward PFC/PWM Controller Combo

GENERAL DESCRIPTION\nThe ML4805 is a controller for power factor corrected, switched mode power supplies. Similar to the ML4801, the ML4805 may be used for voltage mode operation. Key features of this combined PFC and PWM controller are low start-up and operating currents. Power Factor Correction (P ■ Internally synchronized PFC and PWM in one IC\n■ Low start-up current (200µA typ.)\n■ Low operating current (5.5mA typ.)\n■ Low total harmonic distortion\n■ Reduces ripple current in the storage capacitor\n   between the PFC and PWM sections\n■ Average current continuous boost leading edge PFC\n■ ;
