400mA Driving Capability
A highly integrated PWM controller, FAN6862 provides
several features to enhance the performance of flyback
converters. To minimize standby power consumption, a
proprietary green-mode function 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. This green-mode function enables power supplies
to meet international power conservation requirements.
The FAN6862 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 is
proprietary sawtooth compensation for constant output
power limit over universal AC input range. The gate
output is clamped at 18V to protect the external
MOSFET from over-voltage damage.
Applications
General-purpose switch-mode power supplies and
flyback power converters, including:
? Power Adapters
Other protection functions include V DD over-voltage
protection and over-temperature protection. For over-
temperature protection, 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.
