Datasheet STMicroelectronics TSM1012

TSM1012
Low consumption voltage and current controller for battery chargers
and adapters
Datasheet -production data Description
The TSM1012 is a highly integrated solution for
SMPS applications requiring the CV (constant
voltage) and CC (constant current) mode. %
40 QMBTUJD QBDLBHF TheTSM1012 device integrates one voltage
reference and two operational amplifiers (with
ORed outputs -common collectors). Features Constant voltage and constant current control Low consumption Low voltage operation Low external component count Current sink output stage 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.
