EL7640A, EL7641A, EL7642A

TFT-LCD DC/DC with Integrated Amplifiers

FN6270

Rev 0.00

May 15, 2006

The EL7640A, EL7641A, and EL7642A integrate a high

performance boost regulator with 2 LDO controllers for V

Features

• Current mode boost regulator

- Fast transient response

- 1% accurate output voltage

- 18V/3A integrated FET

- >90% efficiency

and V

, a V -slice circuit with adjustable delay and

either one (EL7640A), three (EL7641A), or five amplifiers

(EL7642A) for V and V applications.

COM

GAMMA

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.

• 2.6V to 5.5V V supply

• 2 LDO controllers for V

- 2% output regulation

and V

OFF

Using external low-cost transistors, the LDO controllers

- V -slice circuit

provide tight regulation for V , V

start-up sequence control and fault protection.

, as well as providing

ON OFF

• High speed amplifiers

- 150mA short-circuit output current

- 12V/s slew rate

The amplifiers are ideal for V and V

GAMMA

applications, with 150mA peak output current drive, 12MHz

bandwidth, and 12V/s slew rate. All inputs and outputs are

rail-to-rail.

- 12MHz -3dB bandwidth

- Rail-to-rail inputs and outputs

• Built-in power sequencing

• Internal soft-start

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.

• Multiple overload protection

• Thermal shutdown

Ordering Information

• 32 Ld 5x5 thin QFN package

• Pb-free plus anneal available (RoHS compliant)

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb

and Pb-free soldering operations. Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements

of IPC/JEDEC J STD-020.
