MAXREFDES1048: Two-layer circuit board, 3.3V/3A, wide input range, synchronous, step-down DC-DC converter

The MAX17504 high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 3.5A and generates output voltage from 0.9V to 90% VIN. Built-in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation is accurate to within ±1.1% over -40°C to +125°C. The devices are available in a compact (5mm x 5mm) TQFN lead (Pb)- free package with an exposed pad. Simulation models are available. The MAX17504 features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous mode (DCM) control schemes.
