High Frequency Operation (up to 190 kHz) for
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 100 kHz. FAN6300H is suitable for
high-frequency operation (up to 190 kHz). A built-in HV
startup circuit can provide more startup current to
reduce the startup time of the controller. Once the V DD
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 t off time, which is 38 μs
to 8 μs in FAN6300A and 13 μs to 3 μs in FAN6300H,
FAN6300H
so
FAN6300H can operate at higher switching
frequency than FAN6300A.
Applications
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 V DD drops below the
turn-off threshold voltage, the controller also disables
PWM output. The gate output is clamped at 18 V to
protect the power MOS from high gate-source voltage
conditions. The minimum t OFF 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).
