NCV8855
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 high ? side load switch. The NCV8855 addresses automotive
radio system and instrument cluster power supply requirements. In
addition to the high ? side load switch, the NCV8855 includes a

switch ? mode 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 ultra ? low
quiescent current NCV861x IC forms an eight ? output 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 high ? side switch can be used for a CD / tape mechanism or
switching an electrically ? powered antenna or display unit. In an
instrument cluster application, the NCV8855 can be used to power
