EVALUATION KIT AVAILABLE  
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).  
S High-Power (Up to 6W) Boost Output Providing Up  
to 18V  
S 1.8V or 3.3V Regulator Provides 500mA with  
External npn Transistor  
S One Positive-Gate Voltage Regulator Capable of  
Delivering 20mA at 28V  
S One Negative-Gate Voltage Regulator  
S High-Frequency 2.2MHz Operation  
S Flexible Stand-Alone Sequencing  
S True Shutdown™ Boost Converter  
S Internal Soft-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.  
S Overtemperature Shutdown  
S -40NC to +105NC Operation  
S AEC-Q100 Qualified  
The MAX16928 is available in a 20-pin TSSOP pack-  
age with exposed pad and operates over the -40NC to  
+105NC temperature range.
