® ISL6534 Data Sheet December 21, 2004 FN9134.1 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. A.
