Boost + V Slice + V

Features

COM

The ISL97645A represents an integrated DC/DC regulator

for monitor and notebook applications with screen sizes up

to 20”. The device integrates a boost converter for

• 2.7V to 5.5V Input

• 2.6A Integrated Boost for Up to 20V A_VDD

• Integrated V_ONSlice

generating A_VDD, a V_ONslice circuit, and a high performance

_COMamplifier.

• RESET signal generated by Supply Monitor

• 600kHz/1.2MHz f_S

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.

• V_COMAmplifier

- 30MHz BW

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

High and low levels are programmable, as well as discharge

rate and timing.

- 50V/µs SR

- 400mA Peak Output Current

• UV and OT Protection

The supply monitor can be used to monitor the input voltage

to prevent low voltage operation.

• 24 Ld 4x4 QFN

• Pb-Free Plus Anneal Available (RoHS Compliant)

The integrated V_COMfeatures high speed and drive

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

Applications

V_COMamplifier is capable of driving 400mA peaks, and

100mA continuous output current.

• LCD Monitors (15”+)

• 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.
