High-Efficiency, Quad Output System

Power Supply Controller for Notebook

Computers

Features

• High Performance R Technology

• Fast Transient Response

The ISL62386 controller generates supply voltages for

battery-powered systems. The ISL62386 includes 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 output and a fixed 3.3V output

respectively. Each can deliver up to 100mA. The Channel 2

switching regulator will automatically take over the LDO5

load when programmed to 5V output. This provides a large

power saving and boosts efficiency. The ISL62386 includes

on-board power-up sequencing, one power-good (PGOOD)

output, digital soft-start, and an internal soft-stop output

discharge that prevents 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

• Fixed +3.3V LDO Output with Enable Control

• Fixed +5V LDO 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

• Thermal Monitor and Protection

• Pb-Free (RoHS Compliant)

Applications

The ISL62386 is available in a 32 Ld 5x5 TQFN package,

and 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.
