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.

  • All features

    • Input voltage: Vin: 48 Vdc-60 Vdc; Vaux:15 Vdc.
    • LED output voltage: 24 Vdc-48 Vdc
    • Maximum LED output current: 700 mA
    • Dimming: between 1%-100%
    • No-load: lower than 50 mW @ 60 Vindc
    • Efficiency:
      • Full load: >97%
      • Load over 20% (analog dimming): > 95%
    • Output Ripple Current: <80 mA @worst case 50 Vindc-48 Voutdc
    • Short-circuit protection
    • PCB board: 50 mm x 50 mm single-side PCB
    • RoHS compliant
