EN6337QI – 3 Amp High Efficiency DC-DC Buck Converter with Integrated Inductor


The Enpirion EN6337Q, a high efficiency DC-DC Buck (Step-Down) Converter, with integrated inductor, represents another innovation in low-power switching converters. 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 EN6337QI 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 EN6337QI utilizes an external resistor divider to set the output voltage to any user defined value. In addition, the EN6337QI is pin-to-pin compatible with the EN6347QI 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.
