LM2716 - PWM DC/DC Converter

General Description

The LM2716 is composed of two PWM DC/DC converters.

A buck (step-down) converter is used to generate a fixed output voltage.

A boost (step-up) converter is used to generate an adjustable output voltage.

LM2716 Dual (Step-up and Step-down) PWM DC/DC Converter February 2004 LM2716 Dual (Step-up and Step-down) PWM DC/DC Converter General Description The LM2716 is composed of two PWM DC/DC converters. A buck (step-down) converter is used to generate a fixed output voltage. A boost (step-up) converter is used to generate an adjustable output voltage. Both converters feature low RDSON (0.16Ω and 0.12Ω) 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.
