DESCRIPTION
The TSM1121 integrated circuit incorporates all
sensing circuitry to regulate and protect from over
voltage and under voltage a multiple output power
supply (3.3V, 5V and 12V).
TSM1121 incorporates all the necessary functions
for Housekeeping features which allow safe
operation in all conditions, and very high system
integration.
TSM1121 integrates a precise voltage reference.
APPLICATION
s PC SMPS triple power line housekeeping ic
(3.3V 5V 12V)
