A highly integrated PWM controller, FAN6863 provides
several features to enhance the performance of flyback
converters. To minimize standby power consumption, a
proprietary Green Mode provides off-time modulation to
continuously decrease the switching frequency under
light-load conditions. Under zero-load conditions, the
power supply enters Burst Mode, which completely
shuts off PWM output. Output restarts just before the
supply voltage drops below the UVLO lower limit. Green
Mode enables power supplies to meet international
power conservation requirements.
The FAN6863 is designed for SMPS and integrates a
frequency-hopping function that helps reduce EMI
emission of a power supply with minimum line filters.
The built-in synchronized slope compensation provides
proprietary sawtooth compensation for constant output
power limit over universal AC input range. The gate
output is clamped at 13.5V to protect the external
MOSFET from over-voltage damage.
Other protection functions include SENSE pin Short-
Circuit Protection (SSCP), V DD Over-Voltage Protection
(OVP), and Over-Temperature Protection (OTP). For
OTP, an external NTC thermistor can be applied to
sense the ambient temperature. When V DD OVP or OTP
is activated, an internal latch circuit latches off the
controller. Protection types shown in Table 1.
