ASL2417SHN Datasheet | NXP Semiconductors

Enhanced two channel LED buck driver with limp-home Rev. 4 - 16 September 2019 Product data sheet 1. Introduction The ASL2417SHN is a two 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 ASL2417SHN supports up to two output channels. It means that with one driver IC, 1 or 2 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 ASL2417SHN has a hysteretic buck DC-to-DC topology. With input voltages from 10 V to 80 V, it allows maximum...
