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.

L5963 is a dual step-down switching regulator with internal power switches, high side driver and a low drop-out linear regulator that can operate as standby regulator or normal LDO. All the regulators can be connected directly to the vehicle battery. In addition to an adjustable voltage detector, voltage supervisors are available. The two DC-DC converters can work in free-run condition or synchronize themselves to an external clock. DC/DCs' PWM outputs have a 180° phase shift. The high operating frequency allowed by the synchronization input helps to reduce AM and FM interferences and grants the use of small and low cost inductors and capacitors. This IC finds application in the automotive segment, where load dump protection and wide input voltage range are mandatory. A slug-up package option is available for applications which require heatsink use. In standby condition the device guarantees extremely low quiescent current (25 μA typical @ -40 °C < T < 85 °C)
