EN5339QI 3A High Efficiency, Small Footprint Point-of-Load DC-DC ConverterThe Enpirion EN5339QI is part of a pin compatible family of low-profile, high efficiency synchronous 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 EN5339QI integrates the inductor, controller, power MOSFETs, gate drive and loop compensation in a tiny 4 mm x 6 mm x 1.1mm package with a total solution footprint of only 55mm2. The 1.1mm height and small footprint enables the use of this part where space and available height is at a premium.The simple design and small external 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.
