EN5394QI - 9 Amp “Feature Rich” DC-DC Buck Converter with Integrated InductorThe Enpirion EN5394QI DC-DC Buck (Step-Down) Converter sets a new standard of power density in low-power switching regulators. The total solution footprint is 190 mm2, without compromising efficiency. It has a unique set of features to facilitate ease of use in systems that are sensitive to beat tones. Requiring as little as few as seven external components, the EN5394QI allows for easy design, while reducing the overall solution cost and simplifying the supply chain. The EN5394QI is a complete power system-on-a-chip (PowerSoC) -- integrating the power switches, inductor, gate drive, controller, and loop compensation in a tiny 8 mm x 11 mm package. The 1.85 mm profile and small footprint enables the use of this part where space is at a premium. The EN5394QI utilizes an external resistor divider to set the output voltage to any user defined value. In addition, the EN5394QI is pin compatible with the 6A EN5364QI, therefore if your power requirements should decrease, the transition to the lower power EN5364QI will be seamless. This 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.
