FEATURES  
DESCRIPTION  
The LM3485 is a high efficiency PFET switching  
regulator controller that can be used to quickly and  
easily develop a small, low cost, switching buck  
regulator for a wide range of applications. The  
hysteretic control architecture provides for simple  
design without any control loop stability concerns  
using a wide variety of external components. The  
PFET architecture also allows for low component  
count as well as ultra-low dropout, 100% duty cycle  
operation. Another benefit is high efficiency operation  
at light loads without an increase in output ripple.

Easy to Use Control Methodology  
No Control Loop Compensation Required  
4.5V to 35V Wide Input Range  
1.242V to VIN Adjustable Output Range  
High Efficiency 93%  
±1.3% (±2% Over Temp) Internal Reference  
100% Duty Cycle  
Maximum Operating Frequency > 1MHz  
Current Limit Protection  
Current limit protection is provided by measuring the  
voltage across the PFET’s RDS(ON), thus eliminating  
the need for a sense resistor. The cycle-by-cycle  
current limit can be adjusted with a single resistor,  
ensuring safe operation over a range of output  
currents.
