Part Number : FAN6754MR
Function : Highly Integrated Green-Mode PWM Controller
Manufacturers : Fairchild Semiconductor
Package : SOP 8 Pin Type
Obsolete as of 25-Nov-2012
The highly integrated IC 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, The Device saves PWM pulses by entering deep burst mode. This burst mode function enables the power supply to meet international power conservation requirements.
FAN6754 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. Also, 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.
