PT16752 Overview
The PT16752 is a Headlight LED controller for automotive with high accuracy peak current mode. The device implements a fixed-frequency peak current mode control technique with programmable switching frequency, slope pensation, and soft-start timing. A unique spreadspectrum modulation (SSM) can reduce emission (EMI) at the switching frequency and its harmonics.
