The Future of Analog IC Technology
MP26085
CC/CV Controller
DESCRIPTION
The MP26085 is a voltage and current control IC
integrated a precision voltage reference and a
current source, which is suitable for battery
charger, second controller of switching regulator
systems, and other types of application required
an accurate voltage and current control systems.
This IC compares the DC voltage and the current
level at the output of a switching power supply to
the voltage reference and current limitation,
respectively. It provides a feedback through an
opto-coupler to the PWM controller IC at the
primary side.
The current source is controlled externally, which
can be used to modify the level of current
limitation by offsetting the information coming
from the current sensing resistor.
It is available in an 8-pin TSOT23 package.
