FAN6862R

A highly integrated PWM controller, FAN6862R/L 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 conditions, the power supply enters burst mode, which completely shuts off PWM output. Output restarts just before the supply voltage drops below the UVLO lower limit. This green-mode function enables power supplies to meet international power conservation requirements.

The FAN6862R/L is designed for SMPS and integrates a frequency-hopping function that helps reduce EMI emission of a power supply with minimum line filters. The built-in synchronized slope compensation is proprietary sawtooth compensation for constant output power limit over universal AC input range. The gate output is clamped at 18V to protect the external MOSFET from over-voltage damage.

Other protection functions include V_DD over-voltage protection, over-temperature protection, and overload protection. For over-temperature protection, an external NTC thermistor can be applied to sense the ambient temperature. When OVP, OTP, or OLP is activated, an internal protection circuit switches off the controller.
