Surface Mount LGA Package The LTM®8021 is a 36VIN 500mA, step-down DC/DC
µModule®. Included in the package are the switching
controller, power switches, inductor, and all support
components. Operating over an input voltage range of 3V
to 36V, the LTM8021 supports an output voltage range of
0.8V to 5V, set by a single resistor. Only an output and
bulk input capacitor are needed to finish the design. n n n n n n n Applications n n n The low profile package (2.82mm) enables utilization of
unused space on the bottom of PC boards for high density point of load regulation. A built-in soft-start timer is
adjustable with just a resistor and capacitor.
The LTM8021 is packaged in a thermally enhanced, …
