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.
