双PWM与线性 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.
