  • Product introduction

TPS61061DRBR   具有亮度控制的19V的400mA的开关1MHz的升压转换器,用于白光LED的电源

illustrate

 

该TPS61060/61/62是一种高频率,恒定电流输出同步升压转换器驱动多达5个白光LED。 为了获得最大的安全性,该器件具有集成过电压和一个先进的短路保护,当输出短路到地。 该器件具有1 MHz固定开关频率允许使用小的外部元件,简化可能的EMI问题。 该器件允许电压等级较低价格低廉,小三种不同的输出电容器过电压保护阈值(14 V/18号第V/23号五)。 LED电流是初步建立与外部检测电阻R和反馈电压调节到500 mV或250毫伏,这取决于ILED引脚配置。
