MAX15062AEVKIT#: 3.3V @ 300mA, 4.5 ~ 60V in, Buck

Summary

The MAX15062A evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX15062A 60V, 300mA ultra-small, high-efficiency, synchronous step-down converter. The EV kit operates over a wide 4.5V to 60V input voltage range, and provides up to 300mA at the preset 3.3V output.

The device features undervoltage lockout, overcurrent protection, and thermal shutdown. The EV kit switches at a fixed frequency of 500 kHz, and delivers a peak efficiency of 90% with the supplied components.

The EV kit includes an EN/UVLO PCB pad and jumpers JU1 and JU2 to enable control of the converter output. The MODE PCB pad and jumper JU3 are provided for selecting the mode of operation of the converter. The VCC PCB pad helps measure the internal LDO voltage. An additional RESET PCB pad is available for monitoring the open-drain logic output.

The EV kit comes installed with the MAX15062AATA+ in an 8-pin (2mm x 2mm) lead (Pb)-free/RoHS-compliant TDFN package.
