Product introduction

TPS60230 用 3x3 QFN 封装的 5 通道 125mA 稳定电流的充电泵，用于白光 LED 背光

illustrate

TPS60230电荷泵的优化，在背光的白光LED彩色显示应用用品。该器件提供恒定电流，每个LED由外部电阻设定。电源电压范围为2.7 V至6.5 V和非常适合于由单节锂离子电池供电或三到四个镍镉，镍氢或碱性电池的所有应用。该TPS60230可提供高达25 mA的每个LED，一共有125毫安输入范围从3.1 V至6.5五，效率高的电压，是利用非常低压差一1x/1.5x在Combi机国小数转换技术实现电流源。此外，电流控制的电荷泵可确保低输入电流纹波和EMI。
