TI Piccolo MCU DC/DC LED Developer’s Kit

Application: Lighting
Information type: Reference design
Keywords: boost, buck, dc/dc converter, PWM dimming, sepic
Manufacturer: Texas Instruments
Product: Dev Kit
Technology: Power Management
Theme: LED Lighting

Overview

The DC/DC LED Lighting Developer’s Kit uses a 12 to 36V DC input. This voltage is then redulated and is able to increase or decrease the input voltage.The output is then connected to each of the LED strings and can provide  Independent closed-loop brightness control of eight LED strings with
PWM dimming

Details

Please see the attached LED Lighting guide.  Quick start.

A video is available from the Texas Instruments web site
