Beschreibung

The MAX17681 is a high-voltage, high-efficiency, iso-buck DC-DC converter designed to provide isolated power up to 3W. The device operates over a wide 4.5V to 42V input and uses primary-side feedback to regulate the output voltage.

The MAX17681 uses peak-current-mode control. The low-resistance, on-chip MOSFETs ensure high efficiency at full load while simplifying the PCB layout.

The device is available in a compact 10-pin (3mm x 2mm) TDFN package. Simulation models are available.
