MARKING  
The NCV8855 is a multiple output controller / regulator IC with an  
integrated highside load switch. The NCV8855 addresses automotive  
radio system and instrument cluster power supply requirements. In  
addition to the highside load switch, the NCV8855 includes a  
switchmode power supply (SMPS) buck controller, a 2.5 A SMPS  
buck regulator and two low dropout (LDO) linear regulator  
controllers. The NCV8855 in combination with the ultralow  
quiescent current NCV861x IC forms an eightoutput automotive  
radio or instrument cluster power solution. The NCV8855 has an  
internally set switching frequency of 170 kHz, with a SYNC pin for  
external frequency synchronization.  
The NCV8855 is intended to supply power to various loads, such as  
a tuner, CD logic, audio processor and CD / tape control within a car  
radio. The highside switch can be used for a CD / tape mechanism or  
switching an electricallypowered antenna or display unit. In an  
instrument cluster application, the NCV8855 can be used to power  
graphics display, flash memory and CAN transceivers. In addition, the  
highside switch can be used to limit power to a TFT display during a  
battery overvoltage condition.
