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 EL7640, EL7641, and EL7642 provide tight regulation for VON, VOFF, as well as providing start-up sequence control and fault protection.
The amplifiers EL7640, EL7641, and EL7642 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 EL7640, EL7641, and EL7642 are specified for operation over the -40°C to +85°C temperature range.
