Description

The Enpirion EN5337QI sets a new standard of power density in low-power switching regulators. The total solution footprint is 75 mm2, without compromising efficiency. The input synchronization feature makes the EN5337QI a good solution for systems that are sensitive to beat tones. Requiring as few as six external components, the EN5337QI makes regulator design a breeze.

A complete power system-on-a-chip (PowerSoC), the EN5337QI integrates power switches, Inductor, gate drive, controller, and loop compensation in a tiny 4 mm x 7 mm package. The 1.85 mm profile and small footprint enables the use of this part where space is at a premium. The EN5337QI utilizes an external resistor divider to set the output voltage to any user defined value.
