1、NXP TEA152x STARplug Mini開關電源解決方案關鍵詞：電源管理,AC/DC轉換器,開關電源,SMPS,STARplug Mini,NXP公司的TEA152x系列是低功耗系統(tǒng)的開關電源控制IC,采用高壓EZ-HV SOI工藝和BiCMOS工藝制造,包括高壓功率開關和直接從火線電壓整流的起動電路,通用電源功率高達30W,火線電壓從80 V到276 V,待機功耗低于100mW,主要用在充電器,適配器,STB,DVD,TV/監(jiān)視器待機電源和PC外設.本文介紹了TEA152x主要特性和優(yōu)勢,方框圖以及STARplug Mini演示板主要特性和多種配置電路圖與相應的元件列表.TEA15

2、2x:SMPS ICs for low-power systemsThe 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 Semicond

3、uctor (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 o

4、f 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 sys
