Description

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

EN2340 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, non-isolated DC-DC conversion.

The Enpirion solution significantly helps in system

design and productivity by offering greatly simplified

board

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.
