The highly integrated FAN6604 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, FAN6604 saves PWM pulses by entering "deep" Burst Mode. Burst Mode enables the power supply to meet international power conservation requirements.
FAN6604 also integrates a frequency-hopping function that helps reduce EMI emission of a power supply with minimm line filters. The built-in synchronized slope compensation helps achieve stable peak-current control. Add in current limit to keep constant output power over universal AC input range. The gate output is clamped at 13 V 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 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.
FAN6604 is available in an 8-pin SOP package.
