Product Details

The MAX42406 evaluation kit (EV kit) provides a proven design to evaluate the MAX42406 1.5MHz synchronous buck converter with 10μA quiescent current. The standard EV kit Printed Circuit Board (PCB) comes with a MAX42406AFOB+ (1.5MHz, adjustable output) installed, as well as various test points and jumpers for evaluation. The EV kit output voltage is fixed and easily configured with minimum component changes. The default EV kit is designed to deliver up to 6A with an input voltage of 4.5V to 36V. Output voltage quality can be monitored by observing the PGOOD signal. The MAX42406 EV kit can also be used to evaluate all variants of the MAX42405 and MAX42406.
