專利證書

RSC61**S 是一款帶有半橋驅(qū)動(dòng)的LED恒流控制電路，可用于LLC諧振拓?fù)洹?/p>

電路工作頻率可達(dá)130KHz，輸入電壓范圍高達(dá)600V以上。

RSC61**S 內(nèi)部集成了邏輯輸入信號(hào)處理電路、欠壓檢測電路、過壓保護(hù)電

路、過溫保護(hù)電路、CS反饋信號(hào)整流電路、誤差放大器電路、壓控振蕩電路、電

流過零檢測電路、電平位移電路、半橋驅(qū)動(dòng)電路等模塊。

RSC61**S VCC電源電壓工作范圍為 8V~20V，靜態(tài)工作電流為720uA。

該芯片具有電流過零檢測功能 (ZCD)，可自動(dòng)設(shè)置死區(qū)時(shí)間，防止高端和低端輸

出功率管的同時(shí)導(dǎo)通。
