MP1517DR for antminer S17 hash board repair

MP1517DR is a 3A fixed frequency boost converter, suitable for medium to high current boost, flyback and SEPIC applications. MP1517DR can adjust the output voltage to 25V, and the efficiency is as high as 95%. Soft start, cycle-by-cycle current limit and input under-voltage lockout can prevent overload or damage to sensitive external circuits during startup and output short-circuit conditions. Current mode regulation and external compensation components allow the MP1517DR control loop to be optimized under various input, output and load current conditions. MP1517DR is available in a thermally enhanced QFN16 (4mm x 4mm) package.

Features:

1. 4A peak current limit

2. Low 700mV feedback threshold

3. Internal 150mΩ power switch

4. 2.6V to 25V input range

5. Open load protection
