Advanced Analog Technology AAT1267B
The AAT1267B offers a compact power supply solution to provide all voltages required by a thin-film-transistor (TFT) liquid-crystal display (LCD) panel for TV applications running from a 12V supply rail. It includes a boost and a buck regulator, a positive and a negative regulated charge-pump, a high voltage switch with gate pulse modulation, an operational amplifier, a high accuracy LDO for gamma reference and one open drain RESET output. The current mode boost regulator provides a fast transient response supply voltage for the source drivers.| Part No. | AAT1267B |
