IS801 Overview
Description
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.
Key Features
- Push-pull driver for small transformers
- Single 3.3V or 5V supply
- High primary-side current drive: 5V supply: 500mA (max) 3.3V supply: 500mA (max)
- Low ripple on rectified output permits small output capacitors
- VCC undervoltage detect
- Spread spectrum clocking for EMI
- Thermal shutdown protection
- Small SOT23-5 package
