High-Efficiency Step-Up Converters

for White LED Main and Subdisplay Backlighting

General Description

Features

ꢀ Accurate Current Regulation for Uniform

The MAX1582/MAX1582Y drive up to six white LEDs in

series with a constant current to provide display back-

lighting for two (main and sub-) displays in cell phones

and other handheld devices. This configuration elimi-

nates the need for ballast resistors and expensive fac-

tory calibration. The proprietary dual-output, step-up

pulse-width modulation (PWM) converter includes a low

Illumination

Subdisplays

maximum battery life.

ꢀ Flexible Dimming Control

The MAX1582/MAX1582Y utilize 1MHz current-mode

PWM control to allow small input and output capacitors

and a small inductor, while minimizing ripple on the input

supply and avoiding interference to sensitive circuitry in

the equipment. Integrated overvoltage protection (27V

for the MAX1582 and 18V for the MAX1582Y) eliminates

the need for an external zener diode to protect the IC

from open circuit. Flexible dimming control utilizes either

an analog control signal or direct digital PWM control

without external RC filtering. This also increases dimming

accuracy at low brightness levels. The PWM dimming

signal can be any frequency from 200Hz to 200kHz. Soft-

start eliminates inrush current during startup.
