EN23F0QI

15A Voltage Mode Synchronous Buck PWM

DC-DC Converter with Integrated Inductor

Description

Features

The EN23F0QI 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

12x13x3mm QFN module. It offers high efficiency,

excellent line and load regulation. The EN23F0QI

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 EN23F0QI 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.
