EVALUATION KIT AVAILABLE
MAX16928
Automotive TFT-LCD Power Supply with Boost
Converter and Gate Voltage Regulators
General Description
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).
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.
