TFT-LCD DC-DC Converters with Operational Amplifiers
General Description
The MAX1516A/MAX1517A/MAX1518A include a highperformance step-up
regulator, two linear-
regulator controllers, and high-current operational amplifiers for activematrix thin-film
transistor (TFT) liquid-crystal displays (LCDs). Also included is a logic-controlled, high-voltage switch with adjustable delay.
The step-up DC-DC converter provides the regulated supply voltage for the panel source driver ICs. The converter is a high-frequency (1.2MHz) current-mode
regulator with an integrated 14V n-channel MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loads while achieving efficiencies over 85%.
The gate-on and gate-off linear-
regulator controllers provide regulated TFT gate-on and gate-off supplies using external charge pumps attached to the switching node. The MAX1518A includes five high-per...
