High-Efficiency, Quad or Triple-Output System Power Supply Controller for Notebook

Computers

FN6665

Rev 6.00

October 23, 2015

The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C

and ISL62383C family of controllers generate supply voltages

for battery-powered systems. These controllers include two

Features

• High Performance R Technology

• Fast Transient Response

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 and ISL62383C

have the same outputs as the ISL62381, ISL62382, ISL62381C

and ISL62382C 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. These controllers 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, ISL62381C and ISL62382C are

available in a 32 Ld 5x5 TQFN package, and the ISL62383

and ISL62383C are available in a 28 Ld 4x4 TQFN package.

This family of controllers 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
