High-Efficiency, Triple-Output System
Power Supply Controller for Notebook
Computers
The ISL62391, ISL62392, ISL62391C and ISL62392C
controller generate supply voltages for battery-powered
systems. It includes two pulse-width modulation (PWM)
controllers, adjustable from 0.6V to 5.5V, and a linear
regulator (LDO3) that generates a fixed 3.3V and can deliver
up to 100mA. The ISL62391, ISL62392, ISL62391C and
ISL62392C include on-board power-up sequencing, a
power-good (PGOOD) output, digital soft-start, and 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 28kHz.
The ISL62391, ISL62391C and ISL62392, ISL62392C are
identical except for how their overvoltage protection is
handled. The ISL62391 and ISL62391C utilize a tri-state
overvoltage scheme, whereas the ISL62392 and ISL62392C
employ a soft-crowbar method.
