MAX17521 EVALUATION KIT AVAILABLE 60V, 1A, Dual-Output, High-Efficiency, Synchronous Step-Down DC-DC Converter General Description The MAX17521 dual-output, 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 1A at each output. Each output is programmable from 0.9V to 92%VIN. The feedback voltage regulation accuracy over -40°C to +125°C is ±1.7%. The MAX17521 uses peak-current-mode control. Each output can be operated in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. The MAX17521 is available in a 24-pin (4mm x 5mm) TQFN package. Simulation models are available.
