Evaluation Kit for the MAX17505 in 3.3V Output-Voltage Application
Manufactured By:Maxim Integrated
Part Number:MAX17505EVKITA
The MAX17505 3.3V output evaluation kit (EV kit) provides a proven design to evaluate the MAX17505 high-voltage, high-efficiency, synchronous step-down DC-DC converter. The EV kit is preset for 3.3V output at load currents up to 1.7A and features a 450kHz switching frequency for optimum efficiency and component size. The EV kit features adjustable input undervoltage lockout, adjustable soft-start, open-drain active-low RESET signal, and external frequency synchronization.
The MAX17505 high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. It delivers up to 1.7A and 0.9V to 90%VIN output voltage. Built-in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation accuracy over -40°C to 125°C is ±1.1%. The device is available in a compact (4mm x 4mm) TQFN lead(Pb)-free package with an exposed pad. Simulation models are available.
