This pin is the input of an 8.0 - 450V 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 the voltage at the LD pin, the GATE output goes low.
Ground return for all internal circuitry. This pin must be electrically con-
nected to the ground of the power train.
This pin is the output GATE driver for an external N-channel power
MOSFET.
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.
This is the power supply pin for all internal circuits.
It must be bypassed with a low ESR capacitor to GND (≥0.1μF).
This pin is the linear dimming input and sets the current sense threshold as
long as the voltage at the pin is less than 250mV (typ).
This pin sets the oscillator frequency. When a resistor is connected be-
tween RT and GND, the HV9910B operates in constant frequency mode.
When the resistor is connected between RT and GATE, the IC operates in
constant off-time mode.
