FAN6300

Highly Integrated Quasi-Resonant Current Mode

PWM Controller

Features

Description

The highly integrated FAN6300 PWM controller

provides several features to enhance the performance

of flyback converters. A built-in HV startup circuit can

provide more startup current to reduce the startup time

of the controller. Once the V_DDvoltage exceeds the

turn-on threshold voltage, the HV startup function is

disabled immediately to improve power consumption.

An internal valley voltage detector ensures the power

system operates at Quasi-Resonant operation in wide-

range line voltage and any load conditions and reduces

switching loss to minimize switching voltage on drain of

power MOSFET.

High-Voltage Startup

Quasi-Resonant Operation

Cycle-by-Cycle Current Limiting

Peak-Current-Mode Control

Leading-Edge Blanking

Internal Minimum t_OFF

Internal 2ms Soft-Start

Over-Power Compensation

GATE Output Maximum Voltage

Auto-Recovery Short-Circuit Protection (FB Pin)

Auto-Recovery Open-Loop Protection (FB Pin)

VDD Pin & Output Voltage (DET Pin) OVP Latched

To minimize standby power consumption and light-load

efficiency, a proprietary green-mode function provides

off-time modulation to decrease switching frequency

and perform extended valley voltage switching to keep

to a minimum switching voltage.

FAN6300 controller also provides many protection

functions. Pulse-by-pulse current limiting ensures the

fixed peak current limit level, even when a short circuit

occurs. Once an open-circuit failure occurs in the

feedback loop, the internal protection circuit disables

PWM output immediately. As long as V_DDdrops below

the turn-off threshold voltage, controller also disables

PWM output. The gate output is clamped at 18V to

protect the power MOS from high gate-source voltage

conditions. The minimum t_OFFtime limit prevents the

system frequency from being too high. If the DET pin

reaches OVP, internal OTP is triggered, and the power

system enters latch-mode until AC power is removed.

Applications

AC/DC NB Adapters

Open-Frame SMPS

FAN6300 controller is available in 8-pin SOP and DIP

packages.
