General Description

The MAX5058/MAX5059 enable secondary-side synchronous rectification in isolated power supplies using widely available power MOSFETs.

These devices facilitate the commutation of the secondary-side MOSFETs by providing a clean gate-drive signal that is synchronized to the power MOSFET switching in the primary side of the isolation transformer.

The MAX5058/MAX5059 complement the MAX5051 and MAX5042/MAX5043 primaryside PWM ICs and enable the design of high-efficiency synchronously rectified isolated power supplies.
