LMZ23610EVAL: 1.2/ 2.5/ 3.3/ 5V @ 10A, 6 ~ 36V in

The LMZ23610/8/6 and LMZ22010/8/6 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 LMZ23610/8/6 can accept an input voltage rail between 6V and 36V and the LMZ22010/8/6 can accept an input voltage rail between 6V and 20V.

The current sharing evaluation board is designed so that four modules can be easily connected to supply up to a 40 amp load. More can be connected as long as care is taken to not exceed the current capabilities of the banana plug connectors and the 5-amp per pin rating of the edge board connector.

The current sharing evaluation board is highly configurable. The output voltage can be changed 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. The UVLO can be adjusted by adding one resistor. To simplify the synchronization of the modules an onboard 555 timer provides an adjustable frequency clock from 350 to 600 kHz.

The LMZ23610 and LMZ22010 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.
