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/MAX5.
o Clean Drive Waveforms for Synchronous MOSFETs o Utilization of a Look-Ahead Signal from the Primary for Proper Turn-On/Turn-Off Times o Synchronous Rectifier Drivers Capable of Sourcing and Sinking Up to 2A Peak Current o Internal Gate-Voltage Regulator for 5V (MAX5058) or 10V (MAX5059) Gate-Drive Voltage o Internal Error Amplifier o Accurate Differential Current-Share/Force Circuit Allows Paralleling of Several Power Supplies for High Output Current o Internal Remote Voltage-Sense Amplifier o Flexible Reference-Voltage Generation o Output Voltage Regulation Down to 0.5V o Low Quiescent Curr.
