Analog Devices / Maxim Integrated MAX17574 Synchronous Step-Down DC-DC Converter

Analog Devices MAX17574 Synchronous Step-Down DC-DC Converter is a high-efficiency, high-voltage DC-DC converter with integrated MOSFETs that operates over a 4.5V to 60V input. The Analog Devices converter can deliver up to 3A current. The output voltage is programmable from 0.9V to 90%VIN. The feedback voltage regulation accuracy over -40°C to +125°C is ±0.9%. The MAX17574 features a peak-current-mode control architecture. The device can be operated in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous conduction mode (DCM) control schemes. A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage level. An open-drain active-low RESET pin provides a delayed power-good signal to the system upon successfully regulating the output voltage.
