Product overview
Description
This document describes the EVAL-IBD002-35W demonstration board behavior, designed to manage a dimmable 35 W LED load with a single inverse buck stage.
The HVLED002 controller manages the inverse buck circuitry mainly composed by D1, L1 and Q1 components, able to provide around 700 mA as maximum LED load current.
An external 0-10 V signal is dedicated to managing a dimmed output LED current between 1%-100% of its maximum value with both Analog (100%-10%) and PWM (10%-1%) control.
A 15 Vdc of auxiliary voltage is needed to power up the HVLED002 controller.
