The LM2717 is composed of two PWM DC/DC buck (stepdown)
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 (0.16Ω) 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.
