DESCRIPTION

The TSM111 integrated circuit incorporates all

sensing circuit to control a triple output power supply. It includes voltage references , comparators

and matched resistors bridge for overcurrent and

overvoltage detection without the need of any external components. Timing generator with external

capacitors, control turn On and Off delays. It provides an integrated and cost effective solution for

simultaneous multiple voltage control.

APPLICATION

This circuit is designed to be used in SMPS for

Desktop PC, to supervise currents and voltages of

all outputs and generate power good information

to the system while managing all timing during

transitory operation.

The IC also manages the standby mode of SMPS

while the PC is in sleep mode.
