LM2717  
Dual Step-Down DC/DC Converter  
General Description  
Features  
The LM2717 is composed of two PWM DC/DC buck (step-  
down) converters. The first converter is used to generate a  
fixed output voltage of 3.3V. The second converter is used to  
generate an adjustable output voltage. Both converters fea-  
ture low RDSON (0.16Ω) internal switches for maximum effi-  
ciency. Operating frequency can be adjusted anywhere  
between 300kHz and 600kHz allowing the use of small ex-  
ternal components. External soft-start pins for each enables  
the user to tailor the soft-start times to a specific application.  
Each converter may also be shut down independently with its  
own shutdown pin. The LM2717 is available in a low profile  
24-lead TSSOP package ensuring a low profile overall solu-  
tion.  
Fixed 3.3V output buck converter with a 2.2A, 0.16Ω,  
internal switch  
Adjustable buck converter with a 3.2A, 0.16Ω, internal  
switch  
Operating input voltage range of 4V to 20V  
Input undervoltage protection  
300kHz to 600kHz pin adjustable operating frequency  
Over temperature protection  
Small 24-Lead TSSOP package  
Applications  
TFT-LCD Displays  
Handheld Devices  
Portable Applications  
Laptop Computers
