DESCRIPTION
The TSM111 integrated circuit incorporates all
sensing circuit to control a triple output power sup-
ply. It includes voltage references , comparators
and matched resistors bridge for overcurrent and
overvoltage detection without the need of any ex-
ternal components. Timing generator with external
capacitors, control turn On and Off delays. It pro-
vides 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.
