DESCRIPTION
The TSM101/TSM101A integrated circuit incorpo-
rates a high stability series band gap voltage refer-
ence, two ORed operational amplifiers and a cur-
rent source.
This IC compares the DC voltage and the current
level at the output of a switching power supply to
an internal reference. It provides a feedback
through an optocoupler to the PWM controller IC
in the primary side.
The controlled current generator can be used to
modify the level of current limitation by offsetting
the information coming from the current sensing
resistor.
APPLICATIONS
This circuit is designed to be used in battery
chargers with a constant voltage and a limited out-
put current.
It can be used in every types of application requir-
ing a precision voltage regulation and current limi-
tation.
Other applications include voltage supervisors,
over voltage protection...
