LM2717-ADJ Dual Step-Down DC/DC Converter

Check for Samples: LM2717-ADJ

FEATURES

DESCRIPTION

The LM2717-ADJ is composed 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 R_DSON(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

converter 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 ensuring a low profile

overall solution.
