Description
19-3045; Rev 0; 10/03 www.DataSheet4U.com Parallelable Secondary-Side Synchronous Rectifier Driver and Feedback-Generator Controller ICs General Des.
The MAX5058/MAX5059 enable secondary-side synchronous rectification in isolated power supplies using widely available power MOSFETs.
Features
* 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
Applications
* When used in conjunction with the MAX5051, the primaries can also be synchronized and operated 180 degrees out of phase. The MAX5058/MAX5059 are available in a 28-pin thermally enhanced TSSOP package and operate over a wide -40°C to +125°C temperature range. Warning: The MAX5058/MAX5059 are designe
