TPS54200: output level of Peak Detector circuit

Part Number: TPS54200

Hi Team,

My customer is studying TPS54200 and has a question as below.

Regarding Mode Detection, datasheet says "The internal peak detector at the PWM pin holds the magnitude of the PWM signal" and if customer feed a PWM signal of 50% duty and 0~3V voltage level into PWM pin. The magnitude of "Peak Detector" output signal level is 3V or 1.5V? Since it will affect TPS54200 entering analog dimming mode or PWM dimming mode.

Thanks a lot.
