ASL3417SHN Datasheet | NXP Semiconductors

Enhanced three channel LED buck driver with limp-home Rev. 4 - 16 September 2019 Product data sheet 1. Introduction The ASL3417SHN is a three channel buck mode LED driver IC with a Limp-home mode. It delivers constant average DC current to LEDs independent of the input voltage. The ASL3417SHN supports up to three output channels. It means that with one driver IC 1, 2 or 3 LED strings can be driven independently of each other. It provides a cost effective design solution, specifically targeting automotive exterior and interior lighting applications. 2. General description The ASL3417SHN has a hysteretic buck DC-to-DC topology. With input voltages from 10 V to 80 V, it allows...
