Dual PWM with Linear
The ISL6534 is a versatile triple
regulator that has two independent synchronous-rectified buck controllers with integrated 12V gate drivers (OUT1 and OUT2) and a linear controller (OUT3) to offer precision regulation of up to three voltage rails.
An optional shunt
regulator allows 12V only operation, when a 5V supply is not available.
Each controller has independent soft-start and enable functions combined on a single pin.
