Analog Devices / Maxim Integrated MAX17541G Synchronous Step-Down DC-DC Converter
Analog Devices MAX17541G Synchronous Step-Down DC-DC Converter is a high-efficiency, high-voltage DC-DC converter with integrated MOSFETs operating over 4.5V to 42.0V input. The Analog Devices converter can deliver up to 500mA and generates output voltages from 0.9V up to 0.92% x VIN. The feedback (FB) voltage is accurate to within ±1.7% over -40°C to +125°C. The MAX17541G uses peak-current-mode control with pulse-width modulation (PWM) and operates with a fixed 600kHz switching frequency at any load.
The Analog Devices MAX17541G Synchronous Step-Down DC-DC Converter is in a 3.0mm x 2.0mm TDFN-10 package.
