IS801 Overview
The IS801 is a monolithic oscillator/power-driver, which is designed for small form factor, isolated power supplies in isolated interface applications. A low-profile, center-tapped transformer primary from a 3.3V or 5V DC power supply can be driven by IS801 while the secondary can be wound to provide any isolated voltage based on transformer turns ratio. The IS801 provides the plementary output signals to drive the...
