TSM101AIDT Datasheet PDF - ST Microelectronics

●The TSM101AIDT is a Voltage and Current Controller incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current 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. It can be used in every types of application requiring a precision voltage regulation and current limitation.

● 1.24V Series voltage reference with 10mA output current and 1% precision

● Two operational amplifiers with ORed output and 1MHz gain bandwidth

● Built-in current generator with enable/disable function
