概述

TP8221是一款集成功率管的高精度原边反馈反激型LED恒

流驱动芯片。适合于85VAC~265VAC全电压输入范围的隔

离式LED照明系统应用。

TP8221采用原边反馈的控制方式，通过原边反馈的信息即

可以实现高精度的LED恒流输出，并不需要光耦、次级反馈

等电路。同时，TP8221集成了650V功率管。这精简了外围

元件，节约了系统的成本和体积，简化了LED照明系统的设

计。

TP8221集成了线电压补偿和负载补偿功能，系统具有优异

的线电压调整率和负载调整率。TP8221工作在准谐振开关

模式，功率管处于零电流状态导通。这有效地减小了功率

管的开关损耗，提高了系统效率，同时也改善了系统的EMI

特性。

TP8221工作电压范围宽，适用于85VAC~265VAC全电压

范围的交流输入。同时TP8221集成了多种保护功能以保证

系统的稳定和可靠。包括VCC供电过压保护，VCC供电欠

压保护，LED开路、短路保护，芯片过温保护等。

特点

 内部集成 650V 功率管

 原边反馈恒流控制，无需次级反馈电路

 准谐振开关模式，开关损耗小

 ±3%的 LED 输出电流精度

 优异的线电压调整率和负载调整率
