Description
Error amplifier compensation. Connect the compensation circuit to this pin.
Oscillator control. For free-running operation, connect a resistor between this
pin and AGND. If an external synchronization clock is applied to OSCIN, the ac-
cording resistor must be applied at RT.
Not connected.
Analog dimming input. The input voltage at this pin controls the LED current
sensing at FBH and FBL.
To use internal reference voltage solder to V3V3.
3.3V regulator output. Connect to AGND with a ceramic capacitance of typ. 1µF.
Internal 5V low drop regulator output. Bypass this pin to AGND with a ceramic
capacitance of typ. 1µF. Additionally, the VSM voltage can be connected to DRVS
via a decoupling resistor so supply the CGATEx drivers.
