Compliant BGA Package The LTMВ®8053 is a 40VIN, 3.5A continuous, 6A peak stepdown ВµModuleВ® (power module) regulator. Included in
the package are the switching controller, power switches,
inductor, and all support components. Operating over an
input voltage range of 3.4V to 40V, the LTM8053 supports
an output voltage range of 0.97V to 15V and a switching
frequency range of 200kHz to 3MHz, each set by a single
resistor. Only the input and output filter capacitors are
needed to finish the design.
The low profile package enables utilization of unused
space on the bottom of PC boards for high density point of …
