Overview

® 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.

Key Features

  • Current mode boost regulator - Fast transient response - 1% accurate output voltage - 18V/3A integrated FET - >90% efficiency.
  • 2.6V to 5.5V VIN supply.
  • 2 LDO controllers for VON and VOFF - 2% output regulation - VON-slice circuit.
  • High speed amplifiers - 150mA short-circuit output current - 12V/µs slew rate - 12MHz -3dB bandwidth - Rail-to-rail inputs and outputs.
  • Built-in power sequencing.
  • Internal soft-start.
  • Multiple overload pro.
