LM3495  
Emulated Peak Current Mode Buck Controller for Low  
Output Voltage  
General Description  
Features  
n Input voltage from 2.9V to 18V  
n Output voltage adjustable from 0.6V to 5.5V  
n Feedback Accuracy: 1%  
The LM3495 is a PWM buck regulator which implements a  
unique emulated peak current mode control. This control  
method eliminates the switching noise which typically limits  
current mode operation at extremely short duty cycles and  
high operating frequency. The switching frequency is pro-  
grammable between 200 kHz and 1.5 MHz, and can also be  
synchronized to an external clock. The LM3495 is also very  
fault tolerant with both switch node short, hiccup mode, and  
adaptive duty cycle limit protection. A 0.6V 1% reference and  
glitch free pre-biased start-up ensure the most demanding  
digital loads operate reliably. Internal soft start and the ability  
to track the output of another supply make the LM3495  
versatile and efficient.  
n Low-side Sensing, Programmable Current Limit without  
sense resistor  
n Input Under Voltage Lockout  
n Hiccup mode current limit protection eliminates thermal  
runaway during fault conditions  
n Internal soft start with tracking capability  
n 200 kHz to 1.5 MHz Switching frequency,  
Synchronizable  
n On-chip gate drivers  
n Soft output discharge during shutdown  
n Startup into output pre-bias  
n Operation from a single input rail  
n Adaptive Duty Cycle Limit  
n TSSOP-16 package  
Applications  
n Wide input voltage buck converters with low voltage,  
high accuracy outputs  
n Core logic regulators  
n High-efficiency buck regulation
