TFT-LCD DC/DC With Integrated Amplifiers

The EL7640 EL7641 and EL7642 integrate a high performance boost Regulator with 2 LDO controllers for VON and VOFF, a VON-slice circuit with adjustable delay and either one EL7640 , three EL7641 , or five Amplifiers EL7642 for VCOM and VGAMMA applications.
The boost converter in the EL7640 EL7641 and EL7642 is a current mode PWM type integrating an 18V N-Channel 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 EL7640 EL7641 and EL7642 are specified for operation over the -40C to +85C temperature range.
