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.  
Integrated Inductor, MOSFETs, Controller  
Total Solution Size Estimate 308mm2  
Wide Input Voltage Range: 4.5V – 14V  
2% VOUT Accuracy (Over Line/Load/Temperature)  
Master/Slave Configuration for Parallel Operation  
o Up to 4 Devices with 48A capability  
Frequency Synchronization (External Clock)  
Output Enable Pin and Power OK Signal  
Programmable Soft-Start Time  
Under Voltage Lockout Protection (UVLO)  
Programmable Over Current Protection
