IS801 - Transformer Driver

General Description

The IS801 is a monolithic oscillator/power-driver, which is designed for small form factor, isolated power supplies in isolated interface applications.

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 2.
