DESCRIPTION
The LMZ23610 SIMPLE SWITCHER power module
is an easy-to-use step-down DC-DC solution capable
of driving up to 10A load. The LMZ23610 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ23610 can accept an input voltage rail
between 6V and 36V and deliver an adjustable and
highly accurate output voltage as low as 0.8V. The
LMZ23610 only requires two external resistors and
three external capacitors to complete the power
solution. The LMZ23610 is a reliable and robust
design with the following protection features: thermal
shutdown, input under-voltage lockout, output over-
voltage protection, short-circuit protection, output
current limit, and allows startup into a pre-biased
output. The sync input allows synchronization over
the 350 to 600 kHz switching frequency range.
