Product Details

The MAX15462A evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX15462A 42V, 300mA ultra-small, high- efficiency, synchronous step-down converter. The EV kit operates over a wide 4.5V to 42V 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 500kHz, and delivers a peak efficiency of 90% with the supplied components.

The EV kit comes installed with the MAX15462AATA+ in an 8-pin (2mm x 2mm) lead(Pb)-free/RoHS-compliant TDFN package.
