TEA1623P; TEA1623PH
General description
The TEA1623P; TEA1623PH 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-HVTM SOI process, combined with a low voltage BICMOS process.
The device includes a high voltage power switch and a circuit for start-up directly from the rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible.
In its most basic version of application, the TEA1623P; TEA1623PH acts as a voltage source. Here, no additional secondary electronics are required. A combined voltage and current source can be realized with minimum costs for external components. Implementation of the TEA1623P; TEA1623PH renders an efficient and low cost power supply system.
Features
- Designed for general purpose supplies
- Integrated power switch: 6.5 Ohm and 650 V
- Operates from universal AC mains supplies: 80 V to 276 V
- Adjustable frequency for flexible design
- RC oscillator for load insensitive regulation loop constant
- Valley switching for minimum switch-on loss
- Frequency reduction at low power output for low standby power: <100 mW
- Adjustable overcurrent protection
- Undervoltage protection
- Temperature protection
- Short winding protection
- Safe restart mode for system fault conditions
- Simple application with both primary and secondary (opto) feedback
- Available in 8-pin and 16-pin DIP package.
