60V, Low IQ Synchronous Buck Regulator Enables High Efficiency
The MAX17550 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4V to 60V input. The converter can deliver up to 25mA and generates output voltages from 0.8V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.75% over -40°C to +125°C. The MAX17550 uses peak-current-mode control. The device can be operated in pulse-width modulation (PWM) or pulse-frequency modulation (PFM) modes. The device is available in a 10-pin (3mm x 2mm) TDFN and 10-pin (5mm x 3mm) µMAX® packages. Simulation models are available.
