| Output 2 | 5 V / 0.1 A |
| IC revision | 1 |
Description
The MAX17681EVKITD is a fully assembled and tested circuit board that demonstrates the performance of the MAX17681 high-efficiency, iso-buck DC-DC converter. The EV kit operates over a wide input-voltage range of 17V to 36V and uses primary-side feedback to regulate the output voltage. The EV kit has two output configurations. In the first configuration, the output is programmed to +7V at 200mA, with ±8% output voltage regulation. The second configuration uses a post regulator (MAX17651) to produce +5V at 100mA with at least ±3% regulation. The EV kit comes installed with the MAX17681 in a 10-pin (3mm x 2mm) TDFN package and MAX17651 in a 6-lead TSOT package.
