LV5684PVD数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The LV5684PVD is a power supply IC suitable for USB/CD receiver system for car audio system. This IC integrates 5 systems of regulator output, 2 systems of high side power switch, overcurrent protector, overvoltage protector and overheat protector Supply for VDD and SW33V outputs is low voltage specification, which enables drastic reduction of power dissipation compared to the existing model. (the package is HZIP15).
