FN6665.5
High-Efficiency, Quad or Triple-Output
System Power Supply Controller for
Notebook Computers
The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C
and ISL62383C family of controllers generate supply voltages
for battery-powered systems. These controllers 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 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.
The patented R 3 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.
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.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on
reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see device information
