The MAX20058 is a high-efficiency, high-voltage, synchronous step-down DC-DC converter IC with integrated MOSFETs that operate over a 4.5 to 60V input. The converters can deliver up to 1 A current. The output voltage is programmable from 0.8 V to 90% VIN. The feedback voltage regulation accuracy over -40 to +125 °C is ±1.5%. The IC features a peak-current-mode-control architecture and can be operated in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes.
