IC FAN6754 SMD

original

The FAN6754MR 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 V_DD over-voltage protection. For over-temperature protection, an external NTC thermistor can be applied to sense the external switcher’s temperature. When V_DD OVP or OTP are activated, an internal latch circuit is used to latch-off the controller. The latch mode is reset when the V_DD supply is removed.
