Description
The highly integrated FAN6754B PWM controller
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
and
very
light-load
conditions,
FAN6754B saves PWM pulses by entering deep burst
mode. This burst mode function enables the power
supply to meet international power conservation
requirements.
FAN6754B integrates a frequency-hopping function
internally to reduce EMI emission of a power supply with
minimum line filters. Built-in synchronized slope
compensation is accomplished by proprietary HV
monitor to adjust VLimit for constant output power limit
over universal AC input range. The gate output is
clamped at 13V to protect the external MOSFET from
over-voltage damage.
Other protection functions include AC input brownout
protection with hysteresis, and VDD over-voltage
protection. For over-temperature protection, an external
NTC thermistor can be applied to sense the external
switcher’s temperature. When VDD OVP or OTP are
activated, an internal latch circuit is used to latch-off the
controller. The latch mode is reset when the VDD supply
is removed.
FAN6754B is available in an 8-pin SOP package.
