MAX15020ATP+T — 40 V Input, 2 A Buck Regulator
The MAX15020ATP+T from Analog Devices is a non-synchronous step-down (buck) switching 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. The 20-pin TQFN (5x5 mm) with exposed pad provides a compact footprint for space-constrained designs while the pad aids thermal dissipation when properly soldered to a copper plane.
Temperature grade and deployment environment
The operating junction temperature range of -40 °C to 125 °C qualifies the MAX15020ATP+T for environments such as under-hood automotive and industrial motor drives.
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.
Sourcing and lifecycle
The MAX15020ATP+T carries an Active product status per the manufacturer and is ROHS3 compliant.
