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 VDD voltage 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.
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 VDD drops 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 tOFF time 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.
FAN6300 controller is available in 8-pin SOP and DIP
packages.
