DESCRIPTION
The L5952 is a multifunction 5 output voltage regula-
tor plus a High Side Driver primarily developed for car
radio applications.
Three outputs are enabled and set via I
2
C bus.
Very low stand-by current consumption is achieved
to specifically comply with entertainment and auto-
motive environments.

Before turning on (set turn on procedure), the output voltage should be fixed, as it is done in the initial set pro-
cedure. Do not change the bits of "turn on" and "output voltage" at the same time, otherwise the correct output

voltage may not be present.
Note - example 1 & 2 don't use the OUT2 and OUT6 bytes in the initial set procedure, since these two bytes are not related to the setting of
output voltages

The autoincrement implements a counter by 5, this means that during autoincrement the next date after out 6
byte will be OUT2 date byte.
In the example are refreshed in sequence the bytes: OUT4 - OUT5 - OUT6 - OUT2 - OUT3
