Description

The ALED7707 device consists of an automotive

grade (AEC Q100 compliant) monolithic boost

converter and six controlled current generators

(rows) specifically designed to supply LED arrays

used in the backlighting of LCD panels. The

device can manage an output voltage up to 36 V

(i.e.: 10 white LEDs per row).

The generators can be externally programmed to

sink up to 85 mA and can be dimmed via a PWM

signal (1 dimming duty cycle at 1 kHz can be

managed). The device allows to detect and

manage the open and shorted LED faults and to

let unused rows floating. Basic protections (output

overvoltage, internal MOSFET overcurrent and

thermal shutdown) are provided.

Features

frequency

– External synchronization for multi-device

application

– Pulse skip power saving mode at light load

– Programmable soft-start

– Programmable OVP protection

– Stable with ceramic output capacitors

– Thermal shutdown

? Backlight driver section

– Six rows with 85 mA maximum current

capability (adjustable)

– Rows disable option

– Less than 10 μs minimum dimming on-time

– ± 3 current matching between rows

– LED failure (open and short-circuit)

detection

Applications

? Infotainment LCD backlight

? Daytime running lights

? Car interior/exterior lights

? Dashboard backlight
