com March 4, 2008 LM27 17 Dual Step-Down DC/DC Converter Gener al Description The LM2717 is composed o f two PWM DC/DC buck (stepdown) convert ers.
The first converter is used to gen erate a fixed output voltage of 3.
3V.
T he second converter is used to generate an adjustable output voltage.
Both con verters feature low RDSON (0.
16Ω) int ernal switches for maximum efficiency.
Operating frequency can be adjusted any where between 300kHz and 600kHz allowin g the use of small external components.
External soft-start pins for each enab les the user to .
