Multiple Channels of High Density LED Control for Automotive Headlight Applications
Description
This design: featuring the TMS320F2803x Piccolo microcontroller: implements a high efficiency multi-channel DC-DC LED control system for typically automotive lighting systems. The design support up to 6 channels of LED controls each with maximum of 1.2A current driving capabilities. With a two stage power topology of boost and buck: the system can be operated with a wide input DC voltage from 8V to 20V: which fits perfectly in automotive applications.
Features
- Up to 6 channels of high density DC-DC LED driving capabilityHigh overall efficiency of about 86% at stable maximum outputWide input operation voltage range from 8V to 20VVery low ripple current on each LED channel with +/- 1mA at constant outputControlled and monitored via CAN communication interface with pre-defined open protocol. Easy to adapt to various end users.Over voltage and over current protection. 45V load dump protection
