The Intel® Enpirion® EN5319QI is part of a pin-compatible family of low-profile, high-efficiency synchronous DC-DC step-down (buck) converters. Pin compatibility provides a single solution footprint, enabling a scalable, copy-and-paste solution for embedded computing, FPGAs, ASICs, and embedded processors.
A complete power system-on-a-chip (PowerSoC), the EN5319QI integrates the inductor, controller, power MOSFETs, gate drive, and loop compensation in a tiny 4 mm x 6 mm x 1.1 mm package with a total solution footprint of only 50 mm2. The 1.1 mm height and small footprint allow use of this part in space-constratined applications.
The simple design and brief external bill of materials (BOM) enable fast time to market. The loop compensation can be adjusted to accommodate a range of output filter capacitor requirements. Unlike discrete power products, Enpirion’s turnkey point-of-load power solution gives the designer a complete power system that is fully simulated, characterized, validated, and production qualified.
