Enpirion® Power Datasheet  
EN5319QI 1.5A PowerSoC  
Low Profile Synchronous Buck DC-DC  
Converter with Integrated Inductor  
Description  
Features  
The EN5319QI is a highly integrated, low profile,  
highly efficient, 1.5A synchronous buck power system  
on a chip (PowerSoCTM). The device features an  
advance integrated inductor, integrated MOSFETs, a  
• Integrated Inductor  
• Solution Footprint as Small as 50 mm2  
• Low Profile, 1.1mm  
PWM voltage-mode controller,  
and internal  
• High Reliability Solution: 42,000 Years MTBF  
• High Efficiency, up to 95 %  
compensation providing the smallest possible solution  
size.  
The EN5319QI is a member of the EN53x9QI family  
of pin compatible and interchangeable devices. The  
pin compatibility enables an easy to use scalable  
family of products covering the load range from 1.5A  
up to 3A in a low profile 4mm x 6mm x 1.1mm QFN  
package.  
The EN5319QI operates at high switching frequency  
and allows for the use of tiny MLCC capacitors. It also  
enables a very wide control loop bandwidth providing  
excellent transient performance and reduced output  
impedance. The internal compensation is designed  
for unconditional stability across all operating  
conditions.  
• Low Output Ripple Voltage; <4mVP-P Typical  
• 2.4 V to 5.5 V Input Voltage Range  
• 1.5A Continuous Output Current Capability  
• Output Enable and Power OK Signal  
• Pin Compatible w/ EN5329QI 2A and EN5339QI 3A  
• Under Voltage Lockout, Over Current, Short Circuit,  
and Thermal Protection  
• RoHS Compliant; Halogen Free; 260°C Reflow  
Applications  
Altera’s Enpirion integrated inductor solution  
significantly helps to reduce noise. The complete  
power converter solution enhances productivity by  
offering greatly simplified board design, layout and  
manufacturing requirements. Altera’s Enpirion  
products are RoHS compliant and lead-free  
manufacturing environment compatible.  
• Applications with Low Profile Requirement such as  
SSD and Embedded Computing  
• SAN/NAS Accelerator Appliances  
• FPGA, ASSP, PLD, ASIC, and Processors  
• Noise Sensitive Applications
