FAN6755

Highly Integrated Green-Mode PWM Controller

Features

Description

This highly integrated PWM controller provides several

features to enhance the performance of flyback

converters.

Internal High-Voltage Startup

Low Operating Current (Maximum: 2mA)

Adaptive Decreasing of PWM Frequency to 23KHz

at Light-Load condition to Improve Light-Load

Efficiency

To minimize standby power consumption, a proprietary

adaptive green-mode function reduces switching

frequency at light-load condition. To avoid acoustic-

noise problems, the minimum PWM frequency is set

above 23kHz. This green-mode function enables the

power supply to meet international power conservation

requirements, such as Energy Star^®. With the internal

high-voltage startup circuitry, the power loss caused by

bleeding resistors is also eliminated. To further reduce

power consumption, FAN6755 uses the BiCMOS

process, which allows an operating current of only 2mA.

The standby power consumption can be under 100mW

for most of LCD monitor power supply designs.

Frequency Hopping to Reduce EMI Emission

Fixed PWM Frequency: 65KHz

Internal Leading-Edge Blanking

Built-in Synchronized Slope Compensation

Auto-Restart Protection : Feedback Open-Loop

Protection (OLP), V_DDOver-Voltage Protection

(OVP), Over-Temperature Protection (OTP), and

Line Over-Voltage Protection

FAN6755 integrates a frequency-hopping function that

reduces EMI emission of a power supply with minimum

line filters. Its built-in synchronized slope compensation

Soft Gate Drive with Clamped Output Voltage: 18V

V_DDUnder-Voltage Lockout (UVLO)

achieves

a stable peak-current-mode control and

Programmable Constant Power Limit (Full AC

Input Range)

improves noise immunity. The proprietary, external line

compensation ensures constant output power limit over

Internal OTP Sensor with Hysteresis

Build-in 5ms Soft-Start Function

a wide AC input voltage range from 90V_ACto 264V_AC

FAN6755 provides many protection functions. The

internal feedback open-loop protection circuit protects

the power supply from open feedback loop condition or

output short condition. It also has line under-voltage

protection (brownout protection) and over-voltage

protection using an input voltage sensing pin (V_IN).
