产品描述

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.
