DESCRIPTION
The
LTM
®
8050
is a 58V
IN
, 2A step down µModule
®
(mi-
cromodule) converter. Included in the package are the
switching controller, power switches, inductor and all
support components. Operating over an input voltage
range of 3.6V to 58V, the LTM8050 supports an output
voltage range of 0.8V to 24V and a switching frequency
range of 100kHz to 2.4MHz, each set by a single resistor.
Only the bulk input and output filter capacitors are needed
to finish the design.
The LTM8050 is packaged in a 9mm

ball grid array (BGA) package suitable for automated
assembly by standard surface mount equipment. The
LTM8050 is available with SnPb (BGA) or RoHS compli-
ant terminal finish.
