Evaluation Kit for MAX17531 - Synchronous Step-Down DC-DC Converter
Manufactured By:Maxim Integrated
Part Number:MAX17531AUBEVKIT
The MAX17531AUBEVKIT is an Evaluation Kit for MAX17531, 42V, 50mA, Ultra-Small, High-Efficiency, Synchronous Step-Down DC-DC Converter with 22µA No-Load Supply Current.
The MAX17531 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4V to 42V input. The converter can deliver up to 50mA 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 MAX17531 uses peak-current-mode control and can be operated in pulse-width modulation (PWM) or pulse-frequency modulation (PFM) modes.
