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 capability
  • High overall efficiency of about 86% at stable maximum output
  • Wide input operation voltage range from 8V to 20V
  • Very low ripple current on each LED channel with +/- 1mA at constant output
  • Controlled 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
