The FAN6754A is a highly integrated green-mode PWM controller that provides low standby power consumption and excellent performance for switch-mode power supplies and flyback power converters. It features a proprietary green-mode function that provides off-time modulation to continuously decrease the switching frequency under light-load conditions to minimize standby power consumption. Under zero-load and very light-load conditions, the FAN6754A saves PWM pulses by entering deep burst mode. This burst mode linearly hops between 22 kHz and 65 kHz to reduce EMI emissions.

The FAN6751MR is a highly-integrated green-mode PWM controller with features such as high-voltage startup, low operating current, linearly decreasing PWM frequency, fixed PWM frequency, peak-current-mode control, etc.

The FAN6749 is a highly integrated ultra green-mode PWM controller. It features high voltage startup, low operating current, linearly reducing PWM frequency to 24kHz, proprietary frequency hopping to reduce EMI, two-level over-current protection (OCP), 1400ms delay for normal peak load, two-level OCP, 56ms delay for super peak load, output short-circuit protection (SCP), peak-current mode operation with cycle-by-cycle current limiting, HV pin brown-in/out protection with hysteresis, constant power limit by HV sampling, internal FB open-loop protection (OLP), GATE output maximum voltage clamp: 14.5V, VDD over-voltage protection (OVP), programmable over-temperature protection (OTP), integrated 6ms soft-start function, internal latch circuit (OVP, OTP, OCP, OLP, SCP), internal OTP sensor with hysteresis. It is suitable for general-purpose switched-mode power supplies and flyback power converters, including: power adapters, open-frame SMPS; specifically for SMPS with surge-current output, such as for printer, scanner, motor drivers.

FAN6747 is a highly integrated green-mode PWM controller with features such as high-voltage startup, AC-line brownout protection, constant output power limit, built-in 8ms soft-start function, etc. It is suitable for general-purpose switch-mode power supplies and flyback power converters, such as power adapters, printers, scanners, motor drivers, etc.

FAN6300A/H is a highly integrated quasi-resonant current mode PWM controller from Fairchild Semiconductor. It is suitable for low frequency (below 100kHz) quasi-resonant flyback converters and high frequency (up to 190kHz) flyback converters. The device features high-voltage startup, quasi-resonant operation, cycle-by-cycle current limiting, peak-current-mode control, leading-edge blanking (LEB), internal minimum tOFF, internal 5ms soft-start, over power compensation, GATE output maximum voltage, auto-recovery over-current protection (FB pin), auto-recovery open-loop protection (FB pin) VDD pin and output voltage (DET pin) OVP latched function.

This application note describes the LED driving system using a half-bridge LLC resonant converter for high power LED lighting applications, such as outdoor or street lighting. Due to the existence of the non-isolation DC-DC converter to control the LED current and the light intensity, the conventional PWM DC-DC converter has the problem of low-power conversion efficiency. The half-bridge LLC converter can perform the LED current control and the efficiency can be significantly improved. Moreover, the cost and the volume of the whole LED driving system can be reduced.
