TFT- LCD DC-DC Converters with OP Amp.

The EC9219 include a high-performance step-up regulator, and high-current operational amplifiers for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).The step-up DC-DC converter provides the regulated supply voltage for the panel source driver ICs. The converter is a high-freq 2.6V to 5.5V Input Supply Range1.2MHz or 640KHZ Current-Mode Step-Up RegulatorFast Transient Response to Pulsed LoadHigh-Accuracy Output Voltage ( 2% )Built-In 18V, 1.6A, 0.16Ω N-Channel MOSFETHigh Efficiency (90%)High-Performance Operational Amplifiers17V/μs Slew Rate12MHz, -3dB BandwidthRa;
