EN63A0QI – 12 Amp High Efficiency DC-DC Buck Converter with Integrated Inductor

The Enpirion EN63A0QI, a high efficiency DC-DC Buck (Step-Down) Converter, with integrated inductor, represents another innovation low-power switching converters, setting a new benchmark in power density of 113W/in2. The device showcases a total solution footprint of only 227mm2, and excellent power efficiency over the entire operating temperature range.

A complete power system-on-a chip (PowerSoC), the EN63A0QI integrates power switches, inductor, gate drive, controller, and loop compensation in a tiny 10 mm x 11 mm package. The small footprint also enables the use of this part where space is at a premium, but where compromise in efficiency and power supply noise is NOT permitted.

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.

The EN63A0QI utilizes an external resistor divider to set the output voltage to any user defined value. In addition, the EN63A0QI has a package design which is scalable with the EN6360QI which provides circuit designers the opportunity to build in design tunability for various load requirements.
Enpirion’s power management IC is an excellent choice for low-power applications that require a small solution footprint, while delivering superb efficiency, exceptional thermal performance, low noise, high reliability and ease of use.
