ML4803规格书详情

GENERAL DESCRIPTION

The ML4803 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents. Power Factor Correction (PFC) offers the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply fully compliant to IEC1000-3-2 specifications. The ML4803 includes circuits for the implementation of a leading edge, average current “boost” type PFC and a trailing edge, PWM.

FEATURES

■Internally synchronized PFC and PWM in one 8-pin IC

■Patented one-pin voltage error amplifier with advanced input current shaping technique

■Peak or average current, continuous boost, leading edge PFC (Input Current Shaping Technology)

■High efficiency trailing-edge current mode PWM

■Low supply currents; start-up: 150µA typ., operating: 2mA typ.

■Synchronized leading and trailing edge modulation

■Reduces ripple current in the storage capacitor between the PFC and PWM sections

■Overvoltage, UVLO, and brownout protection

■PFC VCCOVP with PFC Soft Start
