High Efficiency 5V, 10A Buck Regulator  
ISL95210  
Features  
The ISL95210 is a high-efficiency step-down regulator that can  
deliver 10A of output current from a 5V input. The small  
4mmx6mm QFN package and only four external components  
provide a very small total solution size. Low resistance internal  
MOSFETs deliver excellent efficiency and permit full power  
operation in a +90°C ambient without airflow.  
• 10A Continuous Output Current  
• 2.97V to 5.5V Input Voltage Range  
• Up to 95% Efficiency  
• Full Power Operation in +90°C Ambient without Airflow  
• R4™ Control Architecture Delivers Excellent Transient  
Response Without Compensation  
The regulator operates from an input voltage of 2.97V to 5.5V,  
and provides a 0.6% accurate output voltage over the full  
operating temperature range. Intersil's patented R4™ control  
architecture provides exceptional transient response with no  
external compensation components. The output voltage may be  
programmed by an internal DAC or by an external resistor divider  
(see “Output Voltage Programming” on page 11 for more  
details).  
• Pin Selectable Output Voltage Programming  
• ±0.6% Output Voltage Accuracy Over Full Operating  
Temperature Range  
• Programmable Enhanced Light-Load Efficiency Operation  
• Output Voltage Margining and Power-good Monitor  
• Small 6mmx4mm QFN Package  
Several digital control signals provide flexibility for users that  
want additional features. Switching frequency, switching mode,  
output voltage margining and daisy-chained power-good  
functions are all programmed by these pins. The ISL95210 also  
includes comprehensive internal protection for overvoltage,  
undervoltage, overcurrent and over-temperature conditions.  
Applications  
• Point-of-Load Power Supplies  
• Notebook Computer Power  
• General Purpose Power Rail Generation
