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 out-
put voltage. A boost (step-up) converter is used to generate
an adjustable output voltage. Both converters feature low
R
(0.16
and 0.12
) 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 en-
ables the user to tailor the soft-start times to a specific
application. Each converter may also be shut down indepen-
dently with its own shutdown pin. The LM2716 is available in
a low profile 24-lead TSSOP package.
