LN33X61Q1

The LN33X61Q1 is a high efficiency, compact, synchronous step-down LED driver employing a constant frequency, peak current mode control architecture with internal compensation. It operates from an input voltage from 3.5V to 60V and integrates both high-side and low-side power MOSFETs with up to 0.6A/1A/1.5A output capability. The nominal switching frequency is fixed on 400kHz, 1MHz or 2.1MHz.Automatic frequency foldback at light load improvesefficiency.
