Overview

This LED lighting control reference design demonstrates a unique approach to drive and control a string of multiple high-power light-emitting diodes (LEDs). This reference design is targeted for industrial machine vision systems and is also suitable for other industrial or automotive lighting applications. The design allows users to program LED current and timing to enable the safe overdriving of LEDs for increased brightness. The design can operate autonomously but can also be triggered or generate a trigger through an isolated interface. Internal circuit blocks support a wide input voltage range, a programmable input current, and input power control as well as protect against reverse polarity, overvoltage and overtemperature.

Features

LED string voltage up to 24V
Programmability of multiple parameters:
- LED current: 200 mA to 2.4 A
- LED mode: Continuous or pulsed 200 ns to 4.9 s
- LED pulse repetition: 0.2 Hz to 10 kHz
- Trigger delay time: 10 μs for trigger input
- Multi-pulse time, and current bracketing to support AEB and HDR imaging
Cascaded dual power stages:
- Pre-Boost: Wide 8V to 36V, 15-W system input with adaptive inductor current limit
- Buck: Fast inductor current ramping
Isolated trigger and UART interface:
- Isolated 5-V, 50-mA output
- Sinking NPN– and TTL trigger IN and OUT
Comprehensive system supervision and protection:
- Onboard temperature sensors and voltage supervision
- Ultra-fast output overvoltage protection
eFuse: Reverse protection, adaptive overcurrent limit, and input power limit
EEPROM for up to 256 bits of user data
