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. Using external low-cost transistors, the LDO controllers provide tight regulation for VON, VOFF, as well as providing start-up sequence control and fault protection. The amplifiers are ideal for VCOM and VGAMMA applications, with 150mA peak output current drive, 12MHz bandwidth, and 12V/s slew rate. All inputs and outputs are rail-to-rail. Available in the 32 Ld thin QFN (5mm x 5mm) Pb-free packages, the EL7640A, EL7641A, and EL7642A are specified for operation over the -40°C to +85°C temperature range.

EL7640A, EL7641A, EL7642A ® Data Sheet PRELIMINARY May 15, 2006 TFT-LCD DC/DC with Integrated Amplifiers Features 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. Using external low-cost transistors, the LDO controllers provide tight regulation for VON, VOFF, as well as providing start-up sequence control and fault protection. The amplifiers are ideal for VCOM and VGAMMA applications, with 150mA peak output current drive, 12MHz bandwidth, and 12V/µs slew rate. All inputs and outputs are rail-to-rail. Available in the 32 Ld thin QFN (5mm x 5mm) Pb-free packages, the EL7640A, EL7641A, and EL7642A are specified for operation over the -40°C to +85°C temperature range.
