MAX16929

Automotive TFT-LCD Power Supply with Boost

Converter and Gate Voltage Regulators

General Description

Features

The MAX16929 is a highly integrated power supply for

automotive TFT-LCD applications. The device integrates

one buck converter, one boost converter, one 1.8V/3.3V

regulator controller, and two gate voltage regulators.

The device comes in several versions to satisfy com-

mon automotive power-supply requirements (see the

Ordering Information/Selector Guide table).

S Operating Voltage Range of 4V to 28V (Buck) or

3V to 5.5V (Boost)

S Independent 28V Input Buck Converter Powers

TFT Bias Supply Circuitry and External Circuitry

S High-Power (Up to 6W) Boost Output Providing Up

to 18V

S 1.8V or 3.3V Regulator Provides 500mA with

Designed to operate from a single 4V to 28V supply or

5.5V to 28V supply, the device is ideal for automotive

TFT-LCD applications.

External npn Transistor

S One Positive-Gate Voltage Regulator Capable of

Delivering 20mA at 28V

Both the buck and boost converters use spread-spec-

trum modulation to reduce peak interference and to opti-

mize EMI performance.

S One Negative-Gate Voltage Regulator

S High-Frequency Operation

 2.1MHz (Buck Converter)

 2.2MHz (Boost Converter)

The sequencing input (SEQ) allows flexible sequencing

of the positive-gate and negative-gate voltage regulators.

The power-good indicator (PGOOD) indicates a failure

on any of the converters or regulator outputs. Integrated

thermal shutdown circuitry protects the device from over-

heating.

S Flexible Stand-Alone Sequencing

S True Shutdown™ Boost Converter

S 6µA Low-Current Shutdown Mode (Buck)

S Internal Soft-Start

The MAX16929 is available in a 28-pin TSSOP pack-

age with exposed pad, and operates over the -40NC to

+105NC temperature range.

S Overtemperature Shutdown

S -40NC to +105NC Operation
