MAX17506

MAX17506 4.5V–60V, 5A, High-Efficiency, Synchronous Step-Down DC-DC Converter with Internal Compensation General Description The MAX17506 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 60V input. The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.4% over -40°C to 125°C. The MAX17506 uses peak current-mode control. The device can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), and discontinuous conduction mode (DCM) control schemes. The device is available in a 20-pin (5mm x 5mm) Thin QFN (TQFN) package. Simulation models are available.
