3 Description
The LMZ13610 SIMPLE SWITCHER^® power module
is an easy-to-use step-down DC-DC solution capable
of driving up to 10-A load. The LMZ13610 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ13610 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 LMZ13610 only requires two external resistors
and three external capacitors to complete the power
solution. The LMZ13610 is a reliable and robust
design with the following protection features: thermal
shutdown, input undervoltage lockout, output over-
voltage protection, short circuit protection, output
current limit, and allows start-up into a prebiased
output.
