High-Efficiency, 40V Step-Up

MAX1553/MAX1554

General Description

Converters for 2 to 10 White LEDs

Benefits and Features

The MAX1553/MAX1554 drive white LEDs in series with

a constant current to provide efficient display backlight-

ing in cellular phones, PDAs, and other hand-held

devices. The step-up converter includes an internal

• Highly Integrated and Flexible Solution for Wide

Range of Backlighting Applications

• Constant-Current Regulation for Even LED

Illumination

40V, low R

, N-channel MOSFET switch for high

DSON

• Internal 40V MOSFET Switch Capable of Driving

10 LEDs

• 2.7V to 5.5V Input Voltage Range

• Analog or PWM Control of LED Intensity

• Optimized for Low Input Ripple

efficiency and maximum battery life. The MAX1553 has

a current limit of 480mA for driving two to six white

LEDs, while the MAX1554 has a current limit of 970mA

for driving up to 10 white LEDs.

A single analog/PWM Dual Mode™ input provides two

simple means of brightness adjustment. A separate

enable input provides on/off control. Soft-start mini-

mizes inrush current during startup.

• Soft-Start Minimizes Inrush Current

• High Efficiency Improves Battery Life

• Up to 88% Efficiency Driving 6 LEDs

• Up to 82% Efficiency Driving 9 LEDs (20mA,

The MAX1553/MAX1554 are available in space-saving

8-pin TDFN 3mm x 3mm packages.
