Preliminary Datasheet

9A Voltage Mode Synchronous Buck PWM

DC-DC Converter with Integrated Inductor

2Description

Features

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, non-

isolated DC-DC conversion.
