FAN480001S Product details

Description

The highly integrated FAN4800AS/CS/01S/02S parts are specially designed for power supplies that consist of boost PFC and PWM. They require very few external components to achieve versatile protections / compensation. They are available in 16-pin DIP and SOP packages.

The PWM can be used in either current or voltage mode. In voltage mode, feed-forward from the PFC output bus can reduce the secondary output ripple.



Features

■ Pin-to-Pin Compatible with ML4800 and FAN4800 and CM6800 and CM6800A

■ PWM Configurable for Current Mode or Feedforward Voltage-Mode Operation

■ Internally Synchronized Leading-Edge PFC and Trailing-Edge PWM in One IC

■ Low Operating Current

■ Innovative Switching-Charge Multiplier Divider

■ Average-Current Mode for Input-Current Shaping

■ PFC Over-Voltage and Under-Voltage Protections

■ PFC Feedback Open-Loop Protection

■ Cycle-by-Cycle Current Limiting for PFC/PWM

■ Power-on Sequence Control and Soft-Start

■ Brownout Protection

■ Interleaved PFC/PWM Switching

■ Improved Efficiency at Light Load

■ fRTCT=4•fPFC=4•fPWM for FAN4800AS/01S

■ fRTCT=4•fPFC=2•fPWM for FAN4800CS/02S



Applications

■ Desktop PC Power Supply

■ Internet Server Power Supply

■ LCD TV, Monitor Power Supply

■ UPS

■ Battery Charger

■ DC Motor Power Supply

■ Monitor Power Supply

■ Telecom System Power Supply

■ Distributed Power
