3mm Г— 3mm Monolithic DC/DC Boost/Inverting Converters
with 65V Power Switches
Joshua Moore The vast array of power supply rails required by modern electronics has popularized the
use of compact, easy-to-use monolithic DC/DC converters, such as the LT3580 boost/
inverting converter. The LT8580, LT8570, and LT8570-1 build on the success of the LT3580,
increasing the switch voltage to 65V and the input voltage to 40V, while retaining features
and pin compatibility. The LT8580 includes a 65V, 1A power switch, whereas the LT8570 and
LT8570-1 step the switch current limit down to 0.5A and 0.25A, respectively. Various current
options enable application optimizationвЂ”a monolithic converter sized for specific demands
can be smaller and more efficient than one designed for greater load currents. Optimized
sizing for current limit helps limit input and output current in the event of a short or failure.
In addition to the new options, all
devices in the familyвЂ”LTВ®3580, LT8580,
LT8570, and LT8570-1вЂ”are pin compatible. With a few simple component
changes, the same PCB layout can be
used for a range of applications, allowing fast turnaround design changes and
reuse. The LT8580, LT8570, and LT8570-1
retain the LT3580вЂ™s features such as single
resistor feedback, for both positive and
negative output voltages, overtemperature protection, frequency foldback, and an
external clock input pin. And, like the
LT3580, many features are user adjustable, including oscillator frequency,
soft-start, UVLO and output voltage. All …
