The new TSM1052 is a secondary
side controller specific for SMPS
applications requiring a dual
control loop to perform constant
current and constant voltage regulation.
Its extended operating range of
supply from 1.7 to 18V makes this
device the leader in the market
place. The advantage of handling
the lowest input voltage, means
that the SMPS can be implemented
with the lowest number of components
directly connecting the IC to
the output of the SMPS.
The highest voltage capability
increases the device’s robustness
to load transient, safe start-up
and accidental feedback disconnections.
A further advantage is its low
power consumption: with a typical
quiescent current of 150µA,
TSM1052 is suitable for all applications
compliant with the most recent
energy saving regulations. |

| Tiny Space
Saving SOT23-6L Package |
Housed in SOT23-6L, one of the smallest
packages
available, it is ideal for space constrained
applications.
| Brief Functional Description |
The TSM1052 integrates a precise voltage
reference, two operational amplifiers
and a low side current
sensing circuit. The voltage reference,
along with one op-amp, makes up the
voltage control loop while the current
sensing circuit and the other op-amp
make up the current control loop.
