Data Sheet

FN6665.4

High-Efficiency, Quad or Triple-Output

System Power Supply Controller for

Notebook Computers

Features

• High Performance R Technology

• Fast Transient Response

The ISL62381, ISL62382, ISL62383 family of controllers

generate supply voltages for battery-powered systems. The

ISL62381 and ISL62382 include two pulse-width modulation

(PWM) controllers, adjustable from 0.6V to 5.5V, and two

linear regulators, LDO5 and LDO3, that generate a fixed 5V

and an adjustable output respectively, and each can deliver

up to 100mA. The ISL62383 has the same outputs as the

ISL62381 and ISL62382, but without LDO3 linear regulator.

The channel 2 switching regulator will automatically take

over the LDO5 load when programmed to 5V output. This

provides a large power savings and boosts efficiency. The

ISL62381, ISL62382, ISL62383 family include on-board

power-up sequencing, two power-good (PGOOD) outputs,

digital soft-start, and internal soft-stop output discharge that

prevent negative voltages on shutdown.

• ±1% Output Voltage Accuracy: -10°C to +100°C

• Two Fully Programmable Switch-Mode Power Supplies

with Independent Operation

• Programmable Switching Frequency

• Integrated MOSFET Drivers and Bootstrap Diode

• Adjustable (+1.2V to +5V) LDO Output

• Fixed +5V LDO Output with Automatic Switchover to

SMPS2

• Internal Soft-Start and Soft-Stop Output Discharge

• Wide Input Voltage Range: +5.5V to +25V

• Full and Ultrasonic Pulse-Skipping Mode

• Power-Good Indicator

The patented R PWM control scheme provides a low jitter

system with fast response to load transients. Light-load

efficiency is improved with period-stretching discontinuous

conduction mode (DCM) operation. To eliminate noise in

audio frequency applications, an ultrasonic DCM mode is

included, which limits the minimum switching frequency to

approximately 28kHz.

• Overvoltage, Undervoltage and Overcurrent Protection

• Fault Identification by PGOOD Pull-Down Resistance

• Thermal Monitor and Protection

• Pb-Free (RoHS Compliant)

Applications

The ISL62381, ISL62382, is available in 32 Ld 5x5 TQFN

package, and ISL62383 is available in 28 Ld 4x4 TQFN

package. ISL62381, ISL62382, ISL62383 family can operate

over the extended temperature range (-10°C to +100°C).

• Notebook and Sub-Notebook Computers

• PDAs and Mobile Communication Devices

• 3-Cell and 4-Cell Li+ Battery-Powered Devices

• General Purpose Switching Buck Regulators

NOTE: These Intersil Pb-free plastic packaged products employ special

Pb-free material sets; molding compounds/die attach materials and 100%

matte tin plate PLUS ANNEAL - e3 termination finish, which is 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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
