Analog Devices / Maxim Integrated MAX20059 Synchronous Step-Down DC-DC Converter
Analog Devices MAX20059 Synchronous Step-Down DC-DC Converter is a highly efficient IC with integrated MOSFETs that operates over a 4.5V to 72V input voltage range. This DC-DC converter delivers up to 1A current, 0.8V to 90% VIN programmable output voltage, and ±1.5% feedback voltage-regulation accuracy over -40°C to +125°C temperature range. The MAX20059 converter features peak-current-mode-control architecture that can be operated in the Pulse-Width Modulation (PWM) or Pulse-Frequency Modulation (PFM) control schemes. This DC-DC converter is suitable for 48V systems and mild hybrid applications.
