Description
A highly integrated PWM controller, FAN6862H(HR)
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 FAN6862H(HR) is designed for SMPS and
integrates frequency-hopping function internally, which
helps reduce EMI emission of a power supply with
minimum line filters. The built-in synchronized slope
compensation is proprietary saw-tooth 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.
Other protection functions include VDD Over-Voltage
Protection (OVP) and Over-Temperature Protection
(OTP). For over-temperature protection, an external
NTC thermistor can be applied to sense the ambient
temperature. When VDD OVP or OTP is activated, an
internal latch circuit latches off the controller.
