VR11.1 controller in a 40-QFN
The ISL6334DCRZ is a single-output voltage regulator controller designed for Intel VR11.1 processor power delivery. It accepts a 3V to 12V input rail and regulates a 0.5V to 1.6V output, making it a fit for VR11.1-compliant motherboard VRMs.
Housed in a 40-VFQFN exposed-pad package (6x6 mm, 0.5 mm pitch), the part requires a thermal land on the PCB to dissipate heat from the die through the paddle. The Tube packaging means it ships in a standard anti-static tube, not tape-and-reel — factor this into your pick-and-place feeder setup if you are running a reel-only line.
