Quad-Output Automotive
System Power Supply IC
with Integrated High-Side
2A Switch
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, 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.
