The MAX20058 is a high-efficiency, high-voltage, synchronous step-down DC-DC converter IC with integrated MOSFETs that operates over a 4.5V to 60V input. The converters can deliver up to 1A current. Output voltage is programmable from 0.8V to 90%VIN. The feedback voltage-regulation accuracy over -40°C 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.
The MAX20058 is available in a 12-pin (3mm x 3mm) side-wettable TDFN package with an exposed pad for thermal heat dissipation

Evaluation Kits (1)
The MAX20058 EV kit is a proven design to evaluate the MAX20058 high-efficiency, high-voltage, synchronous step-down DC-DC converter in a TDFN package. The EV kit is optimized to generate a 5V output at load currents up to 1A from a 24V input supply and can be reconfigured to meet other system requirements. The EV kit features a 400kHz switching frequency. The EV kit can be used to monitor the IC’s features such as adjustable input undervoltage lockout, adjustable soft-start, adjustable switching frequency, adjustable current limit, open-drain active-low RESET signal, and external frequency synchronization.
