3 Description
The LMZ13608 SIMPLE SWITCHER® power module
is an easy-to-use step-down DC-DC solution capable
of driving up to 8-A load. The LMZ13608 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ13608 can accept an input voltage rail
between 6 V and 36 V and can deliver an adjustable
and highly accurate output voltage as low as 0.8 V.
The LMZ13608 only requires two external resistors
and three external capacitors to complete the power
solution. The LMZ13608 is a reliable and robust
design with the following protection features: thermal
shutdown, input undervoltage lockout, output
overvoltage protection, short circuit protection, output
current limit, and the device allows start-up into a
prebiased output.
