LM2717-ADJ  
Dual Step-Down DC/DC Converter  
General Description  
Features  
n Adjustable buck converter with a 2.2A, 0.16, internal  
switch (Buck 1)  
The LM2717-ADJ is composed of two PWM DC/DC buck  
(step-down) converters. Both converters are used to gener-  
ate an adjustable output voltage as low as 1.267V. Both also  
feature low RDSON (0.16) internal switches for maximum  
efficiency. Operating frequency can be adjusted anywhere  
between 300kHz and 600kHz allowing the use of small  
external components. External soft-start pins for each con-  
verter 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-ADJ  
is available in a low profile 24-lead TSSOP package ensur-  
ing a low profile overall solution.  
n Adjustable buck converter with a 3.2A, 0.16, internal  
switch (Buck 2)  
n Operating input voltage range of 4V to 20V  
n Input undervoltage protection  
n 300kHz to 600kHz pin adjustable operating frequency  
n Over temperature protection  
n Small 24-Lead TSSOP package  
Applications  
n TFT-LCD Displays  
n Handheld Devices  
n Portable Applications  
n Laptop Computers  
n Automotive Applications
