EN6347QI – 4 Amp High Efficiency DC-DC Buck Converter with Integrated Inductor
The Enpirion EN6347QI, a high efficiency DC-DC Buck (Step-Down) Converter, with integrated inductor, represents another innovation in low-power switching converters, setting a new benchmark in power density of 113W/in2. The total solution footprint is only 75mm2, while showcasing excellent power efficiency over the entire operating temperature range.
A complete power system-on-a chip (PowerSoC), the EN6347QI integrates power switches, inductor, gate drive, controller, and loop compensation in a tiny 4 mm x 7 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 EN6347QI utilizes an external resistor divider to set the output voltage to any user defined value. In addition, the EN6347QI is pin-to-pin compatible with the EN6337QI and EN5337QI, 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.
