MAX25611A/MAX25611B/

MAX25611C/MAX25611D

Automotive High-Voltage HB LED Controller

General Description

The MAX25611A/MAX25611B/MAX25611C/MAX25611D

Beneﬁts and Features

● Automotive Ready: AEC-Q100 Qualified

are single-channel HBLED drivers for automo-

tive front light applications such as high beam,

low beam, daytime running light (DRL), turn

indicator, fog light, and other LED lights. It can take an

input voltage from 5V to 36V and can drive a string of

LEDs with a maximum output voltage of 65V.

● Integration Minimizes BOM for High-Brightness

LED Driver

• Integrated pMOS Dimming FET Gate Driver Allows

Single-Wire Connection to LED String

• PWM, Analog-to-PWM and Analog Dimming

• Integrated High-Side, Current-Sense Ampliﬁer

• 12-Pin SWTQFN-EP Package

The MAX25611A/B/C/D sense output current at

the high side of the LED string. High-side current

sensing is required to protect for shorts from the output

to the ground or battery input. It is also the most flex-

ible scheme for driving LEDs, allowing boost, high-side

buck, SEPIC mode, or buck-boost mode configura-

tions. The PWM input provides LED dimming ratios of

up to 5000:1, and the REFI input provides additional

analog dimming capability in the MAX25611A/B/C/D.

The MAX25611A/B/C/D have built-in spread-spectrum

modulation for improved electromagnetic compat-

ibility performance. The MAX25611A/B/C/D can also

be used in zeta and Cuk converter configurations if it is

necessary in some applications.

● Flexible Application Configurations

• +5V to +36V Wide Input Voltage Range with a

Maximum +65V Boost Output

• Boost, Buck-Boost, High-Side Buck, SEPIC, Zeta,

and Cuk Single-Channel LED Drivers

● Protection Features and Wide Temperature Range

Increase System Reliability

• Short-Circuit, Overvoltage, and Thermal Protection

• -40°C to +125°C Operating Temperature Range

Ordering Information appears at end of data sheet.

Simpliﬁed Application Circuit

The MAX25611A/B/C/D are available in a space-saving

12-pin SWTQFN-EP package. They are specified to oper-

ate over the -40°C to +125°C automotive temperature

range. The switching frequency is internally set at 350kHz

for the MAX25611A/MAX25611C and 2.2MHz for the

MAX25611B/MAX25611D.

Applications

● Automotive Exterior Lighting

● High Beam/Low Beam/Signal/Position Lights

● Daytime Running Lights (DRLs)

● Fog Lights and Adaptive Front-Light Assemblies

● Head-Up Displays

● Commercial, Industrial, and Architectural Lighting
