DESCRIPTION
The LM2717-ADJ is posed of two PWM DC/DC buck (step-down) converters. Both converters are used to generate an adjustable output voltage as low as 1.267V. Both also feature low RDSON (0.16Ω) internal switches for maximum efficiency. Operating frequency can be adjusted anywhere between 300k Hz and 600k Hz allowing the use of small external ponents. External soft-start pins for each converter enables the user to tailor the soft-start times to a specific application. Each converter may also be shut down independently...
