The MAXM17623/MAXM17624 evaluation kits (EV kits) provide a proven design to evaluate the performance of the MAXM17623/MAXM17624 modules. Each of these modules are configured to demonstrate optimum performance and component sizes in the EV kits.
The MAXM17623 module delivers up to 1A at a switching frequency of 2MHz. The module is configured for a 1.5V output over a 2.9V to 5.5V input range.
The MAXM17624 module delivers up to 1A at a switching frequency of 4MHz. The module is configured for a 3.3V output over a 3.6V to 5.5V input range.
The EV kits feature provisions for selecting Mode of operation (pulse-width modulation and pulse-frequency modulation) and Enable input. The MAXM17623/MAXM17624 module data sheet provides a complete description of the parts that should be read in conjunction with this EV kit data sheet prior to operating the EV kits.
