TEA152x family
General description
The TEA152x family STARplug+ 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. 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 TEA152x family 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 TEA152x family renders an efficient and low cost power supply system.
Features
- Designed for general purpose supplies up to 30 W
- Integrated power switch:
- TEA1520: 48 Ohm; 650 V
- TEA1521: 24 Ohm; 650 V
- TEA1522: 12 Ohm; 650 V
- TEA1523: 6.5 Ohm; 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 makes low standby power possible (< 100 mW)
- Adjustable overcurrent protection
- Undervoltage protection
- Temperature protection
- Short-circuit winding protection
- Simple application with both primary and secondary (opto) feedback
- Available in DIP8 and SO14 packages
