Description
The EN2390QI is a Power System on a Chip (PowerSoC) DC-DC converter. It integrates MOSFET switches, small-signal control circuits, compensation and an integrated inductor in an advanced 11x10x3mm QFN module. It offers high efficiency, excellent line and load regulation over temperature.
The EN2390QI operates over a wide input voltage range and is specifically designed to meet the precise voltage and fast transient requirements of high performance products. The EN2390 features frequency synchronization to an external clock, power OK output voltage monitor, programmable soft-start along with thermal and over current protection. The device’s advanced circuit design, ultra high switching frequency and proprietary integrated inductor technology delivers high-quality, ultra compact, nonisolated DC-DC conversion.
The Enpirion solution significantly helps in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements. In addition, overall system level reliability is improved given the small number of components required with the Enpirion solution.
All Enpirion products are RoHS compliant and lead free manufacturing environment compatible.
