Evaluation Setup

Here the evaluation of TPS922051D1DSGREVM is used as an example.

Input voltage is set at 48 V. Load is 8 white LEDs (Part Number: GW PUSTA1.CM-MENE-XX53-1 from OSRAM) in series. The frequency of the input PWM signal (Low level: 0V, High level: 3.3V) at the DIM pin is set to 1kHz. The duty cycle of the input PWM signal is set to 50%.
