Description
The highly integrated FAN6300A/H of PWM controller
provides several features to enhance the performance
of flyback converters. FAN6300A is applied on quasi-
resonant flyback converters where maximum operating
frequency is below 100kHz. FAN6300H is suitable for
high-frequency operation (up to 190kHz). 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 reduce
power consumption. An internal valley voltage detector
ensures power system operates at quasi-resonant
operation over a wide-range of line voltage and any
load conditions, as well as reducing 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. The operating
frequency is limited by minimum toff time, which is 38s
to 8s in FAN6300A and 13s to 3s in FAN6300H, so
FAN6300H can operate at higher switching frequency
than FAN6300A.
FAN6300A/H 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, the 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 triggers OVP, internal OTP is triggered and
the power system enters latch-mode until AC power is
removed.
The FAN6300A/H controller is available in the 8-pin
Small Outline Package (SOP) and the Dual Inline
Package (DIP).
