FN9228.0

Boost + LDO + V Slice + V

The ISL97644 represents an integrated DC/DC regulator for

monitor and notebook applications with screen sizes up to

20”. The device integrates a boost converter for generating

Features

• 3V to 5.5V Input

COM

• 2.6A Integrated Boost for Up to 20V A_VDD

• Integrated V_ONSlice

_VDD, a V_ONslice circuit, an integrated logic LDO and a high

performance V_COMamplifier.

• 350mA V_LOGICLDO

The boost converter features a 2.6A FET and has user

programmable soft-start and compensation. With efficiencies

up to 92%, the A_VDDis user selectable from 7V to 20V.

- 2.5V, 2.85V, 3.3V Output Voltage Selectable

• 600kHz/1.2MHz f_S

• V_COMAmplifier

- 30MHz BW

- 50V/µs SR

The logic LDO includes a 350mA FET for driving the low

voltage needed by the external digital circuitry.

The V_ONslice circuit can control gate voltages up to 30V.

High and low levels are programmable, as well as discharge

rate and timing.

- 400mA Peak Output Current

• UV and OT Protection

• 24 Ld 4x4 QFN

The integrated V_COMfeatures high speed and drive

capability. With 30MHz bandwidth and 50V/µs slew rate, the

• Pb-Free Plus Anneal Available (RoHS Compliant)

_COMamplifier is capable of driving 400mA peaks, and

Applications

100mA continuous output current.

• LCD Monitors (15”+)

Pinout

• Notebook Display (up to 16”)

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.
