説明
The MAX17623/MAX17624 evaluation kits (EV kits) provide a proven design to evaluate the performance of the MAX17623/MAX17624 converters. Each of these devices operates over an input range from 2.9V to 5.5V and delivers up to 1A output current. The devices are configured to demonstrate optimum performance and component sizes in the EV kits.
The MAX17623 converter delivers up to 1A at a switching frequency of 2MHz. The converter is configured for a 1.5V output over a 2.9V to 5.5V input range.
The MAX17624 converter delivers up to 1A at a switching frequency of 4MHz. The converter 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 (PWM/PFM) enabling or disabling the output and PGOOD signal. The MAX17623/MAX17624 converter data sheet provides a complete description of the parts, that should be read in conjunction with this data sheet prior to operating the EV kits.
