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

PIN CONNECTIONS (top view)

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...
