sPMIC for Micro-Converter Bias and Drivers
ISL1801
The ISL1801 is a power management IC (PMIC) optimized for
solar array micro-converters and other systems operating from
a high voltage DC supply. The ISL1801 can be used in buck,
boost or buck-boost micro-converter topologies in order to
maximize the energy harvest from a solar array. In addition to
the power stage and main controller, the ISL1801 includes the
bias regulators, gate drivers, current sense amplifier and
comparators needed for micro-converters.
The ISL1801 integrates two switching regulators that can be
used to generate the driver and the micro-controller (MCU)
power supplies. In addition, it has a low offset, low drift
amplifier for current sensing, two comparators for overvoltage
and overcurrent protection plus a watch-dog timer to reset the
MCU if necessary. This single IC solution offers high integration
and dramatically reduces the total number of components in
the micro-converter system improving the system reliability
and reducing cost.
The first regulator takes input voltages ranging from 9V to 90V
from the solar panel and outputs a regulated supply for drivers
and the secondary regulator. The secondary regulator converts
the output of the first regulator to a programmable
micro-controller supply, typically 3.3V. A high voltage start-up
LDO provides the necessary bias voltage until the switching
regulator is operating.
The ISL1801 integrates two high speed MOSFET drivers for
Buck, Flyback or Boost converters configured as shown in the
application schematics. The Drive3 also has the integrated
peak current limiting capabilities.
The ISL1801 includes comprehensive start-up, shutdown and
fault logic to ensure reliable operation of micro-converters in
solar applications.
