MAX20096/MAX20097

Dual-Channel Synchronous Buck, High-Brightness

LED Controller with and without SPI Interface

General Description

Beneﬁts and Features

The MAX20096/MAX20097 are dual-channel, high-

voltage, synchronous n-channel high-current buck LED

drivers. The ICs use a proprietary average current-mode-

control scheme to regulate the inductor current. This

control method does not require any control-loop compen-

sation, maintaining nearly constant switching frequency.

Inductor current sense is achieved by sensing the current

in the bottom switching device. The ICs integrate two fully

synchronous buck-converter controllers, and operate over

a wide 4.5V to 65V input range. The ICs are designed for

high-frequency operation and can operate at switching

frequencies as high as 1MHz.

● Integration Minimizes BOM for High-Brightness LED

Driver, Saving Space and Cost

• Wide 4.5V to 65V Input Voltage Range

• No Compensation Components

• Programmable Switching Frequency

• External MOSFETs that are Sizable for the

Appropriate Current

● Wide Dimming Ratio Allows High-Contrast Ratio

• Analog Dimming

• PWM Dimming

● Suitable for Matrix Lighting

• Maintains Current Regulation While Shorting/

Opening Individual LEDs in the String

• Ultra-Fast Response Control Loop Prevents

Overshoots and Undershoots

In the MAX20096, the output voltages and currents on

both channels and the junction temperature can be read

back through the SPI interface. Protection features include

inductor current-limit protection, overvoltage protection,

and thermal shutdown. The MAX20096 is available in a

space-saving thermally enhanced (5mm x 5mm), 32-pin

side-wettable TQFN package and is specified to operate

over the -40°C to +125°C automotive temperature range.

● Protection Features and Wide Temperature Range

Increase System Reliability

• Short Circuit, Overvoltage, and Thermal Protection

• -40ºC to +125ºC Operating Temperature Range

• Thermal Monitor and LED Current Monitor

The MAX20097 is available in a 28-pin thermally enhanced

TSSOP package, but does not have the SPI interface. It

includes an open-drain fault flag (FLTB) that goes low

in case of an open string, shorted string, or overvoltage

activation in any one of the channels, or also in thermal

shutdown.

● Fault Diagnosis Through SPI Interface and Through

FLTB Pin for Applications without SPI Interface

Applications

● Automotive Exterior Lighting

Ordering Information appears at end of data sheet.

• High-Beam/Low-Beam/Signal/Position Lights

• Daytime Running Lights (DRLs)

• Fog Light and Adaptive Front Light Assemblies

● Commercial, Industrial, and Architectural Lighting
