MAX16928

Automotive TFT-LCD Power Supply with Boost

Converter and Gate Voltage Regulators

General Description

Features

The MAX16928 is a highly integrated power supply

for automotive TFT-LCD applications. The device inte-

grates one boost converter, one 1.8V/3.3V regulator

controller, and two gate voltage regulators. The device

comes in several versions to satisfy common automotive

TFT-LCD power-supply requirements (see the Ordering

Information table).

SꢀInternalꢀSoft-Start

The boost converter uses spread-spectrum modulation to

reduce peak interference and to optimize EMI performance.

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.

The MAX16928 is available in a 20-pin TSSOP pack-

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

+105NC temperature range.
