MAX16923

Automotive 4-Output Display Power Solution

with Watchdog

General Description

Benefits and Features

The MAX16923 is a 4-channel power-management IC de-

signed to accommodate the main rails used in modern

automotive TFT displays. The MAX16923 and the

MAX20069 TFT power supply and LED backlight driver

combine to provide a two-chip solution to all automotive

display power supply requirements.

● High Integration

• Complete Display Power Solution from Automotive

Battery

• One High-Voltage 2.1A Buck Converter (5V or

3.3V)

• One High-Voltage 100mA Low-I Linear Regulator

(3.3V)

The MAX16923 integrates a high-voltage buck converter

that transforms battery voltages into a 5V or 3.3V interme-

diate rail. In addition, a high-voltage, always-on, low qui-

escent current linear regulator supplies power at 3.3V.

• One Low-Voltage 1.6A Buck Converter (3.3V, 1.8V,

1.2V, or 1.1V)

• One Low-Voltage Linear Regulator (3.3V, 1.8V,

1.5V, or 1.0V)

The low-voltage section consists of a fully-integrated DC/

DC converter and an LDO running off the intermediate rail.

Section output power is available in several low-voltage

combinations (see the Ordering Information table). In ad-

dition, an integrated watchdog timer guards against run-

away code.

• MAX16923GTPB: 75mA

• MAX16923GTPC/MAX16923GTPE: 175mA

• All other variants: 180mA

• Power-Good Outputs

● Integrated Watchdog Timer

● Robust and Low EMI

A single START control pin initiates the start-up sequence,

thereby simplifying device control. The MAX16923's ex-

ternal pMOSFET control block allows battery voltage to

be switched to a downstream device, such as a backlight

boost converter.

● • Programmable Switching Frequency

• Internal Spread Spectrum Oscillator

• Slew-Rate Controlled Switching

• Thermal Shutdown Protection

● Compact TQFN20 4mm x 4mm Package

The MAX16923 is available in a TQFN package and oper-

ates in the -40°C to 105°C temperature range.

Ordering Information appears at end of datasheet.
