TLV61046A是一款高度集成型升压转换器,专为PMOLED面板,LCD偏置电源和传感器模块等应用而设计.TLV61046A集成了30V电源开关,输入至输出的隔离开关以及整流器二极管。该器件可将来自一节锂离子电池或两节碱性电池(串联)的输入电压转换成高达28V的输出电压。
TLV61046A的工作开关频率为1.0MHz。通过将TLV61046A的FB引脚和VIN引脚相连,可将其默认内部输出电压设置为12V。因此,只需要三个外部组件即可获得12V输出电压.TLV61046A的开关限流典型值为980mA。它具有7ms内置软启动时间,从而能够降低浪涌电流.TLV61046A处于关断模式时,隔离开关会将输出与输入断开以最大限度降低泄漏电流.TLV61046A还具有输出短路保护,输出过压保护和热关断。
TLV61046A采用6引脚,3mm x 3mm SOT 23-6封装。
