General description
The TEA1622P is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It is implemented in the high voltage EZ-HV™ SOI process, combined with a low voltage BICMOS process.
Features
â Designed for general purpose supplies
â Integrated power switch: 12â¦and 650 V
â Operates from universal AC mains supplies: 80 V to 276 V
â Adjustable frequency for flexible design
â RC oscillator for load insensitive regulation loop constant
â Valley switching for minimum switch-on loss
â Frequency reduction at low power output for low standby power: <100 mW
â Adjustable overcurrent protection
â Undervoltage protection
â Temperature protection
â Short winding protection
â Safe restart mode for system fault conditions
â Simple application with both primary and secondary (opto) feedback
â Available in 8-pin DIP package.
