Thiscircuit is designedtobeusedin SMPSforDesktop PC, tosupervise currentsandvoltagesof alloutputs 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.

Note : 1. All vol tages values, except dif ferential voltage, are with respect to network ground terminal.

The TSM111 integrated circuit incorporates all sensing circuit to control a triple output power supply. It includes voltage references, comparatorsand matched resistors bridge for overcurrent and overvoltage detection without the need of any external components.Timing generatorwith externalcapacitors, control turn On and Off delays. TSM111 provides an integrated and cost effective solution for simultaneous multiple voltage control.
