DESCRIPTION
The LTM ? 8027 is a complete 4A, DC/DC step-down power
supply. Included in the package are the switching control-
ler, power switches, inductor and all support components.
Operating over an input voltage range of 4.5V to 60V (7.5V
minimum voltage to start), the LTM8027 supports output
voltages up to 24V, and a switching frequency range of
100kHz to 500kHz, each set by a single resistor. Only the
bulk input and output filter capacitors are needed to finish
the design.
The low profile package (4.32mm) enables utilization of
unused space on the bottom of PC boards for high den-
sity point of load regulation. A built-in soft-start timer is
adjustable with a small capacitor.
The LTM8027 is packaged in a thermally enhanced, compact
(15mm × 15mm) and low profile (4.32mm) over-molded
land grid array (LGA) package suitable for automated
assembly by standard surface mount equipment. The
LTM8027 is Pb-free and RoHS compliant.
