TPS92692-Q1: Analog dimming. Leds are alway on

Part Number: TPS92692-Q1

Hello,

I want to use the boost driver with analog dimming. Therefore I set the PWM Pin constant to 3.3V and I change the voltage of the analog pin.

The LEDs pulse/flicker even though the analog voltage is below the threshold voltage. Also, the Light output is not constant. The LEDs are always flickering.

Input voltage 18V and Output voltage 50V. The LED needs a minimum voltage of 30V.
