AN-2134 LMZ13610/8/6 and LMZ12010/8/6 Evaluation
Board
1 Introduction
The LMZ13610/8/6 and LMZ12010/8/6 SIMPLE SWITCHER
®
power modules are easy-to-use DC-DC
solution capable of driving up to a 10, 8 or 6 ampere load. They are available in an innovative package
that enhances thermal performance and allows for hand or machine soldering. The LMZ13610/8/6 can
accept an input voltage rail between 6V and 36V and the LMZ12010/8/6 can accept an input voltage rail
between 6V and 20V.
The evaluation board is highly configurable. The output voltage can be adjusted to 5V, 3.3V, 2.5V or 1.2V
with a jumper change. The external soft-start capacitor facilitates a controlled and adjustable startup rise
time of the output. The board temperature can be measured with the onboard resistor and the UVLO can
be adjusted by changing one resistor. In addition the board comes preconfigured with an LC input filter to
pass CISPR-22 class B conducted and radiated emissions.
The LMZ13610 and LMZ12010 family is a reliable and robust solution with the following features: loss-less
cycle-by-cycle valley current limit to protect for over current or short-circuit fault, thermal shutdown, input
under-voltage lockout, and will start up into a pre-biased output.
