Highly Integrated Quasi-Resonant PWM Controller
Abstract
This application note describes a detailed design strategy for
higher-power conversion efficiency and better EMI using a
Quasi-Resonant
PWM
controller
compared
to
the
conventional, hard-switched converter with a fixed
switching frequency. Based on the proposed design
guideline, a design example with detailed parameters
demonstrates the performance of the controller.
Introduction
The highly integrated FAN6300/A/H PWM controller
provides several features to enhance the performance of
flyback converters. FAN6300/A are applied on Quasi-
Resonant flyback converter where maximum operating
frequency is below 100kHz and FAN6300H is suitable for
high frequency operation that is around 190kHz. A built-in
High Voltage (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 in quasi-resonant operation in wide-
range line voltage and reduces switching loss to minimize
switching voltage on drain of the power MOSFET.
To minimize standby power consumption and improve 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/A/H
controller
provides
many
protection
functions. Pulse-by-pulse current limiting ensures the fixed
peak current limit level, even when 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 the 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 level, internal
OTP is triggered, and the power system enters latch-mode
until AC power is removed.
