DESCRIPTION
TSM1051 is a highly integrated solution for SMPS
applications requiring CV (constant voltage) and
CC (constant current) mode.
TSM1051 integrates one voltage reference, two
operational amplifiers (with ORed outputs -
common collectors), and a current sensing circuit.
The voltage reference combined with one
operational amplifier makes it an ideal voltage
controller, and the other low voltage reference
combined with the other operational amplifier
makes it an ideal current limiter for output low side
current sensing.
The current threshold is fixed, and precise.
The only external components are:
* a resistor bridge to be connected to the output of
the power supply (adapter, battery charger) to set
the voltage regulation by dividing the desired
output voltage to match the internal voltage
reference value.
* a sense resistor having a value and allowable
dissipation power which need to be chosen
according to the internal voltage threshold.
* optional compensation components (R and C).
TSM1051, housed in one of the smallest package
available, is ideal for space shrinked applications
such as adapters and battery chargers.
