DESCRIPTION  
Integrated Power MOSFETs with 6-A  
Continuous Output Current  
TPS53314 is a D-CAP™ mode, 6-A synchronous  
switcher with integrated MOSFETs. It is designed for  
ease of use, low external component count, and  
small package power systems.  
•
•
<10-μA Shut Down Current  
Auto-Skip Eco-mode™ for Light-Load  
Efficiency  
This device features single-rail input support, one  
20-mΩ and one 7.5-mΩ integrated MOSFET,  
accurate 1%, 0.6 V Reference, and integrated boost  
switch. A sample of competitive features include:  
greater than 96% maximum efficiency, 3 V to 15 V  
wide input voltage range, very low external  
component count, D-CAP™ mode control for super  
fast transient, selectable auto-skip and PWM  
operation, internal soft-start control, adjustable  
frequency, and no need for compensation.  
•
