Intel/Altera EN2340QI

The EN2340QI 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 8x11x3mm QFN module. It offers high efficiency, excellent line and load regulation over temperature and up to the full 4A load range. The EN2340QI 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 EN2340QI 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, integrated inductor technology delivers high-quality, and non-isolated DC-DC conversion.

All Enpirion products are RoHS compliant, halogen free and are compatible with lead-free manufacturing environments.
