MAX17686

4.5V to 60V Input, High-Efficiency, Iso-Buck DC-DC Converter

Reduces External Components and Cost for DC-DC Isolation


点击查看特定型号的库存状况。

说明

The Rainier series of isolated DC-DC products enable small, efficient solutions with a lower BOM cost. The MAX17686 is a high-voltage, high-efficiency, iso-buck DC-DC converter designed to provide isolated power up to 5W. The device operates over a wide 4.5V to 60V input and uses primary-side feedback to regulate the output voltage.

The MAX17686 uses peak-current-mode control. The lowresistance, on-chip MOSFETs ensure high efficiency at full load while simplifying the PCB layout.

The device generates a well regulated primary side voltage which is then scaled by a suitable transformer turns ratio to derive isolated secondary output rails. The MAX17686 features robust overcurrent protection on both the primary and secondary side.

The MAX17686 is available in a compact 10-pin (3mm x 2mm) TDFN package. Simulation model and design automation are available in EE-Sim.
