DESCRIPTION
The LTM^®8020 is a complete 200mA, DC/DC step down
power supply. Included in the package are the switch-
ing controller, power switches, inductor, and all support
components. Operating over an input voltage range of 4V
to 36V, the LTM8020 supports an output voltage range of
1.25V to 5V, set by a single resistor. Only bulk capacitors
are needed to finish the design.
The low profile (2.32mm) tiny package enables utilization
of unused space on the bottom of PC boards for high
density point of load regulation.
The LTM8020 is packaged in a thermally enhanced,
compact (6.25mm × 6.25mm) and low profile (2.32mm)
over-molded Land Grid Array (LGA) package suitable for
automated assembly by standard surface mount equip-
ment. The LTM8020 is Pb-free and RoHS compliant.
