Maxim Integrated Products MAX16831: High-voltage LED driver withstands harsh operating environments
May 29 2007 11:55AM | Permalink |Comments (0) |
Targeting automotive and general-lighting applications, the MAX16831 high-voltage, high-power, constant-current LED driver features analog and PWM (pulse-width-modulation) dimming. The device integrates a floating LED current-sensing amplifier and a dimming MOSFET driver, reducing the component count and providing a high reliability in applications using HB (high-brightness) LEDs. Suiting harsh operating environments, the device has a 5.4 to 76V operating input-voltage range, allowing cold start and an 80V load-dump compliance. Aiming at front-light automotive designs, the device suits high- and low-beam assemblies, adaptive front-light systems, DRLs (daytime running lights), and fog lamps. Available in a TQFN-32 package, the MAX16831 costs $2.33 (1000).
