High-Efficiency, 26V Step-Up Converter

for White LED Main and Subdisplay Backlighting

General Description

Features

ꢀ Accurate Current Regulation for Uniform

The MAX1582 drives up to six white LEDs in series with

a constant current to provide display backlighting for

two (main and sub-) displays in cell phones and other

hand-held devices. This configuration eliminates the

need for ballast resistors and expensive factory calibra-

tion. The proprietary dual-output, step-up pulse-width

Illumination

ꢀ Lights Up Two LED Sections for Main and

Subdisplays

ꢀ Up to 84% Efficiency

ꢀ Internal High-Power, 30V MOSFET

modulation (PWM) converter includes a 30V, low R

DSON

N-channel MOSFET switch for high efficiency and maxi-

mum battery life.

ꢀ Low 15mV

Input Ripple

P-P

ꢀ Flexible Dimming Control

The MAX1582 utilizes 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 equip-

ment. Integrated overvoltage protection 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 with-

out 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.

Analog DAC Controlled

Direct-Digital PWM (No RC Required)

from 200Hz to 200kHz

ꢀ Overvoltage Protection to Eliminate Zener Diode

ꢀ Constant 1MHz PWM Operation

ꢀ Low-Profile Inductor and Capacitors

ꢀ Soft-Start Eliminates Inrush Current

ꢀ 2.6V to 5.5V Input

ꢀ 0.01µA (typ) Shutdown Current

ꢀ Tiny UCSP (2.1mm ✕ 2.1mm ✕ 0.61mm) and Thin

QFN (4mm ✕ 4mm) Packages

The MAX1582 is available in tiny 4 ✕ 4 chip-scale

(UCSP™) and 12-pin thin QFN packages.
