Product Details

The MAX15046B evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX15046B 10A synchronous step-down controller. The MAX15046 IC is available in a small 16-pin QSOP package with an exposed pad.

The MAX15046B EV kit requires a 5V to 40V input-voltage range power supply that provides up to 7A for normal operation. The MAX15046B EV kit output is configured to 3.3V and delivers up to 10A output current. The controller's switching frequency is programmed to 350kHz. The MAX15046B EV kit includes PCB pads to enable the circuit and to monitor the power-good output.
