MAX15020ATP+T — 40 V Input, 2 A Buck Regulator
It delivers an adjustable output from 0.5 V to 36 V from a 7.5 V to 40 V input supply. Rated for 2 A continuous output current, the part uses an external Schottky diode (non-synchronous topology) and switches between 300 kHz and 500 kHz, a range that balances inductor size against switching losses for most industrial loads.
Non-synchronous topology — BOM impact
Because the MAX15020ATP+T does not integrate synchronous rectification, the output stage requires an external Schottky catch diode. This adds one component to the BOM but avoids the high-side/low-side shoot-through protection complexity of a synchronous converter. For designs where light-load efficiency is secondary to simplicity and cost, the external diode approach is a practical trade-off.
