Automotive Four-Switch Buck-Boost LED

MAX25603

Controller for Combination Head Lights

General Description

Benefits and Features

The MAX25603 is a synchronous four-switch, buck-

boost LED driver controller suitable for multifunction

automotive combination head lamps. The controller

regulates the LED current for LED string voltages from

0V to 60V. The MAX25603 can be used as a seamless

buck-boost LED driver for applications that require an

efficient buck-boost LED driver with synchronous

rectification. The MAX25603 is ideal for high-power

applications that require a current source with PWM

dimming capability.

•

Automotive Ready: AEC-Q100 Qualified

Integration Minimizes BOM for High-Brightness LED

Driver, Saving Space and Reducing Cost

• Wide Input Voltage Range from 5V to 60V

• H-Bridge Single Inductor Buck-Boost Architecture

• Built-In Fast LED Current Limit During Transients

• Suitable for Dual-String Applications with Time-

Sharing

• 28-Pin TSSOP with EP Pad

•

Full Featured Dual String Driver

• Analog and PWM Dimming on Both Channels

(EN1 and EN2)

• Analog Devices’ Proprietary Control Architecture

Limits LED Current Spikes and Spike Duration in

Dual-String Mode

• Flicker-Free PWM Dimming with Spread-

Spectrum

• Dual Integrated pMOS Dimming FET Gate Driver

The device provides seamless transition between buck,

boost, and buck-boost modes depending on the ratio of

input to output voltage. The MAX25603 is ideal for LED

driver applications in automotive, industrial, and other

LED lighting applications. A fault flag indicates open LED

or thermal shutdown conditions. The device uses Analog

Devices’ proprietary average-current-mode control

scheme and allows adjustable 200kHz to 440kHz fixed-

frequency operation. In addition, ±6% triangular spread-

spectrum is added internally to the oscillator to improve

EMI performance. The MAX25603 provides both analog

and digital PWM dimming in dual string applications with

time sharing. A single device can be used to power a

daytime running light (DRL), position light, high beam,

and low beam in an automotive front headlamp. The

MAX25603 integrates two high-side pMOS drivers for

PWM dimming applications that require fast rising and

falling edges of the LED current. It also features robust

output open and short protection, is AEC qualified, and

is suitable for automotive applications.

Range

Ordering Information appears at end of data sheet

The MAX25603 uses Analog Devices’ proprietary

architecture to limit LED current overshoots and

overshoot durations during switchover in dual-string

applications in time-sharing mode. In multistring

applications in time-sharing mode, LED current

overshoots during switchover between strings is

minimized by an Analog Devices’ proprietary control

scheme.
