TEA1521T

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 Bipolar Complementary Metal-Oxide Semiconductor (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.

  Designed for general purpose supplies up to 30 W

Integrated power switch:

TEA1520x: 48 Ω; 650 V

TEA1521x: 24 Ω; 650 V

TEA1522x: 12 Ω; 650 V

TEA1523P: 6.5 Ω; 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
