1 / 20 page 1. General description The TEA1623 is a Switched Mode Power Supply (SMPS) controller IC that operates directly from 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 TEA1623 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 TEA1623 renders an efficient and low cost power supply system. 2. Features and benefits Designed for general purpose power supplies Integrated power switch: 6.5 Ω and 650 V Operates from universal AC mains supplies: 80 V to 276 V Adjustable frequency for flexible design RC oscillator for stable output regulation Valley switching for minimum switch-on loss Frequency reduction at low power output for low standby power: < 100 mW Adjustable OverCurrent Protection (OCP) UnderVoltage Protection (UVP) 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 packages. 3. Applications Adapters Set-Top Box (STB) DVD VCD CD(R) PC Silverbox standby SMPS TEA1623P; TEA1623PH STARplug switched mode power supply controller IC Rev. 3 — 30 August 2010 Product data sheet |
