EL7642 General Description

The EL7640, EL7641, and EL7642 integrate a high performance boost regulator with 2 LDO controllers for VON and V_OFF, a V_ON-slice circuit with adjustable delay and either one (EL7640), three (EL7641), or five amplifiers (EL7642) for V_COMand 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 V_ON, V_OFF, as well as providing start-up sequence control and fault protection.

The amplifiers are ideal for V_COM 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.
