DESCRIPTION
The LTM ? 8023 is a complete 2A, DC/DC step-down power
supply. 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 36V, the
LTM8023 supports an output voltage range of 0.8V to 10V,
and a switching frequency range of 200kHz to 2.4MHz,
each set by a single resistor. Only the bulk 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 load regulation.
The LTM8023 is packaged in a thermally enhanced, com-
pact and low profile over-molded land grid array (LGA)
and ball grid array (BGA) packages suitable for automated
assembly by standard surface mount equipment. The
LTM8023 is available with SnPb (BGA) or RoHS compli-
ant terminal finish.
