CPwr_PI33xx

Description

The Cool Power PI33XX/34XX 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.
