Analog Devices / Maxim Integrated MAX17686 Iso-Buck DC-DC Converter
Analog Devices MAX17686 Iso-Buck DC-DC Converter enables small, efficient solutions with a lower BOM cost. The MAX17686 is a high-voltage, high-efficiency, iso-buck DC-DC converter that provides isolated power up to 5W. The device operates over a 4.5V to 60V input and uses primary-side feedback to regulate the output voltage. The MAX17686 uses peak-current-mode control. The low-resistance, on-chip MOSFETs ensure high full-load efficiency while simplifying the PCB layout.
