PT16752 Multi-Topology Automotive Headlight LED Driver DESCRIPTION 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 compensation, and soft-start timing. A unique spreadspectrum modulation (SSM) can reduce emission (EMI) at the switching frequency and its harmonics. The controller is designed to support a range of step-up or step-down driver topologies. It incorporates a high voltage (65V) rail-to-rail current sense amplifier that can directly measure LED current using a high-side series sense resistor.
