EN5339QI Buck PowerSoC

Enpirion's 3 A, low-profile, synchronous buck DC-DC converter with integrated inductor

Enpirion's EN5339QI is a highly integrated, low-profile, highly-efficient 3 A synchronous buck power system on a chip (PowerSoC). The device features an advance integrated inductor, integrated MOSFETs, a PWM voltage-mode controller, and internal compensation providing the smallest possible solution size.

The EN5339QI PowerSoC is designed specifically to meet the driving demand for higher power density by providing a fully integrated buck converter into a tiny 4x6x1.1 mm 24-pin QFN package. It features high efficiency, excellent line and load regulation, and guarantees the full 3 A output current over temperature. It operates at a high switching frequency and allows for the use of tiny MLCC capacitors.
