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.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTM8023E is guaranteed to meet performance specifications
from 0°C to 85°C ambient. Specifications over the full –40°C to
85°C ambient operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTM8023I is guaranteed to meet specifications over the full –40°C to 85°C
ambient operating temperature range. The LTM8023MP is guaranteed to
meet specifications over the full –55°C to 125°C temperature range. Note
that the maximum internal temperature is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 3: COUT = 51µF is composed of a 4.7µF ceramic capacitor in parallel
with a 47µF electrolytic.
Note 4: Guaranteed by design.
Note 5: Short circuit current at VIN = 36V is guaranteed by characterization
and correlation. 100% tested at VIN = 10V
