® EL7640A, EL7641A, EL7642A Data Sheet May 15, 2006 FN6270.0 PRELIMINARY TFT-LCD DC/DC with Integrated Amplifiers The EL7640A, EL7641A, and EL7642A integrate a high performance boost regulator with 2 LDO controllers for VON and VOFF, a VON-slice circuit with adjustable delay and either one (EL7640A), three (EL7641A), or five amplifiers (EL7642A) for VCOM and VGAMMA applications. The boost converter in the EL7640A, EL7641A, and EL7642A is a current mode PWM type integrating an 18V NHchannel MOSFET. Operating at 1.2MHz, this boost can operate in either P-mode for superior transient response, or in PI-mode for tighter output regulation.
