Data Sheet
February 4, 2009
FN6831.0
High-Efficiency, Quad Output System
Power Supply Controller for Notebook
Computers
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.
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 ISL62386 is available in a 32 Ld 5x5 TQFN package,
and can operate over the extended temperature range
(-10°C to +100°C).
