The Intel® Enpirion® EP5388QI is an 800 mA point-of-load PowerSoC DC-DC step-down (buck) converter with an integrated inductor that achieves a total solution footprint as small as 28 mm2, without compromising efficiency.
A complete power system-on-a-chip (PowerSoC), the EP5388QI integrates power switches, inductor, gate drive, controller, and compensation in a tiny 3 mm x 3 mm package. The 1.1 mm profile and small footprint enable use of this part when space is at a premium. In addition, this point-of-load solution requires only two external components, reducing the overall solution cost and simplifying the supply chain.
The EP5388QI utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels, or an external voltage divider can be employed to set the output voltage.
This step-down converter power management IC is an excellent choice for low-power applications that require a small solution footprint, high efficiency, exceptional thermal performance, low noise, high reliability, and ease of use.
