FEATURES  
DESCRIPTION  
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 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  
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 solution.
