Datasheet Summary
Preliminary
RT9913A/B
Integrated Multi-Channel DC-DC Converter for
TFT LCD Panels
General Description
Features
The RT9913A/B includes a high-performance boost regulator, one linear-regulator controller for VGL, one low dropout linear regulator, a gate pulse modulator (GPM), a voltage detector and a V Buffer (Unity- gain OPA) for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).
The boost converter provides the regulated supply voltage for the panel source driver ICs. With integrated 16V N-Channel 0.2Ω MOSFET it allows the use of ultra-small inductors and ceramic capacitors and provides fast transient response to pulsed loads. The VGL linear-regulator...
