ISL6521
PWM Buck DC-DC and Triple Linear
Power Controller
The ISL6521 provides the power control and protection for
four output voltages in low-voltage, high-performance
applications. The IC integrates a voltage-mode PWM
controller and three linear controllers, as well as monitoring
and protection functions into a 16-lead SOIC package. The
PWM controller is intended to regulate the low voltage
supply that requires the greatest amount of current (usually
the core voltage for the FPGA, ASIC, or processor) with a
synchronous rectified buck converter. The linears are
intended to regulate other system voltages, such as I/O
(input/output) and memory circuits. Both the switching
regulator and linear voltage reference provide ?% of static
regulation over line, load, and temperature ranges. All
outputs are user-adjustable by means of an external resistor
divider. All linear controllers can supply up to 120mA with no
external pass devices. Employing bipolar NPNs for the pass
transistors, the linear regulators can achieve output currents
of 3A or higher with proper device selection.
The ISL6521 monitors all the output voltages. The PWM
controllers adjustable overcurrent function monitors the
output current by using the voltage drop across the upper
MOSFETs r
DS(ON)
. The linear regulator outputs are
monitored via the FB pins for undervoltage events.
