Switched Mode Power Supply Controller 14-Pin SO T/R

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

• Designed for general purpose supplies up to 30 W
• Integrated power switch: 6.5 O; 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
