IS801 - Transformer Driver

Description

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

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.
