Product Details
The MAX17574, high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 3A current. 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 the 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.
