Built-in 8ms Soft-Start Function
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 V Limit 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 V DD over-voltage
protection. For over-temperature protection, an external
NTC thermistor can be applied to sense the external
switcher’s temperature. When V DD OVP or OTP are
activated, an internal latch circuit is used to latch-off the
controller. The latch mode is reset when the V DD supply
is removed.
Applications
