MAX25520

Automotive 2-Channel TFT-LCD Power Supply

General Description

Benefits and Features

The MAX25520 is a dual-output power IC that provides

symmetrical or asymmetrical positive and negative volt-

ages up to 10.5V and down to -10.5V (±12V for

MAX25520ATEC) with an input voltage between 2.65V

and 5.5V. It incorporates a fully integrated current-mode

boost converter and a current-mode inverter with external

rectifier. The device operates at one of two switching fre-

quencies, 420kHz or 2.1MHz. Operation at 2.1MHz per-

mits very compact dual-output power supplies.

● High Integration

• Synchronous Boost Provides Positive Output at up

to 10.5V/200mA (+12V for MAX25520ATEC)

• Inverter Output Provides up to -10.5V/-200mA

(-12V for MAX25520ATEC)

● Low EMI

• 420kHz/2.1MHz Switching Frequency

• Spread Spectrum

● UV Diagnostics on All Outputs

● Versatile

The two output voltages can be programmed indepen-

dently or can be made to track each other. Independent

enable pins allow complete flexibility in powering the out-

puts up and down.

• Complete Sequencing Flexibility

• Compact TQFN Package

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

The outputs are protected against overcurrent and under-

voltage.

● AEC-Q100 Grade 1

The MAX25520 is available in a compact, 3mm x 3mm

TQFN package and operates over the -40°C to +125°C

automotive temperature range.

Applications

● Infotainment Displays

● Central Information Displays

● Instrument Clusters
