Analog Devices / Maxim Integrated MAX17575 Synchronous Step-Down DC/DC Converters
Analog Devices MAX17575 Synchronous Step-Down DC/DC Converters are high-efficiency, high-voltage ICs with integrated MOSFETs that operate over a 4.5V to 60V input. The MAX17575 delivers up to 1.5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.2% over -40°C to +125°C. The Analog Devices MAX17575 uses peak current-mode control and is available in a 12-pin (3x3mm) TDFN package.
