The MAX1875 evaluation kit (EV kit) demonstrates a low-cost application circuit. This dual-PWM synchronous DC-to-DC converter operates from unregulated AC adapters and generates precision, low-voltage rails for broadband gateways, digital TVs, cable modems, and set-top boxes.
The MAX1875 EV kit provides dual 1.8V and 3.3V output voltages from an 8V to 18V input voltage range. It delivers up to 3.5A output current for the 1.8V output and the 3.3V output, with greater than 90% efficiency. Both converters operate 180 degrees out-of-phase to reduce input ripple current. The EV kit operates at 100kHz switching frequency.
This EV kit is a fully assembled and tested circuit board. It also allows evaluation of other output voltages in the 0.75V to 15V range.
The MAX1875 EV kit can also be used to evaluate the MAX1876 and MAX1858.
