FAN6754 Green-Mode PWM Controller for Flyback Converter 65KHz SOP-8 - Biasa

- Varian yg biasa (kw) markingnya F - #39;Fairchild #39; Yg asli sudah memakai marking ON - #39;ON Semiconductor #39;. Fairchild sudah diakuisisi ON Semiconductor sehingga semua part yg dulunya dimiliki Fairchild akan diganti dengan marking ON (gambar 2). Varian #39;Original ON #39; adalah produk asli dari ON Semiconductor (Fairchild). Mfr.Part # : FAN6754WAMRMY The highly integrated FAN6754A 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, FAN6754A saves PWM pulses by entering deep burst mode. This burst mode function enables the power supply to meet international power conservation requirements. FAN6754A 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, SENSE pin short-circuit protection, and VDD over-voltage protection. For overtemperature 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. FAN6754A is available in an 8-pin SOP package.
