Description

The PI33xx/PI34xx integrates the controller, power switches, and support components all within a
high-density, low-profile Land Grid Array (LGA)
System-in-Package (SiP) offering low thermal and electrical impedance to the PC board. The PI33xx/PI34xx requires only an external inductor and minimal capacitors to form a complete DC-DC switching-mode buck regulator with no design or settings required for basic operation. The PI33xx also offers a rich feature set allowing for various power options including interleaving multiple buck regulators.
