Description
The TSM1011 is a highly integrated solution for
SMPS applications requiring CV (constant
voltage) and CC (constant current) modes.
The TSM1011 device integrates one voltage
reference and two operational amplifiers (with
ORed outputs - common collectors).
The voltage reference combined with one
operational amplifier makes it an ideal voltage
controller. The other operational amplifier,
combined with few external resistors and the
voltage reference, can be used as a current
limiter.
