MAX1518B
EVALUATION KIT AVAILABLE
TFT-LCD DC-DC Converter with Operational Amplifiers
General Description
The MAX1518B includes a high-performance step-up
regulator, two linear-
regulator controllers, and high-current operational amplifiers for active-matrix, 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 transien...
