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.
The EN5337QI is an excellent choice for applications that are sensitive to noise, voltage ripple, and beat frequencies.
