Description
This pin is the input of a 15V-500V linear regulator.
This pin is the current sense pin used to sense the FET current by means of an
external sense resistor. When this pin exceeds the lower of either the internal
250mV or 10 percents of the voltage at the LD pin, the gate output goes low. When
this pin is higher then 350mV, the IC will be latch until UVLO.
Ground
Gate driver output to drive the external MOSEFET
This is the PWM dimming input of the IC. When this pin is pulled to GND, the
gate driver is turned off. When the pin is pulled high, the gate driver operates
normally. Internal 100K Ω resistor pulls it up to 5V.
This is the power supply pin for all internal circuits.
It must be bypassed with a low ESR capacitor to GND.
This pin is the linear dimming input and sets the current sense threshold as long as
the voltage at the pin is less than 2.5V (typ). When this pin is lower then 0.5V,
Gate will be pull down, until its voltage raise to 1V.
This pin sets the oscillator frequency. When a resistor is connected between RT
and GND, the FT881 operates in constant frequency mode. When the resistor is
connected between RT and GATE, the IC operates in constant off-time mode.
