STMicroelectronics TSM1011
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.FEATURES
● Constant voltage and constant current control● Low voltage operation
● Low external component count
● Current sink output stage
● Easy compensation
● 2 kV ESD protection
● Voltage reference: – Fixed output voltage reference 2.545 V – 0.5% and 1% voltage precision
APPLICATIONS
● Adapters● Battery chargers
DESCRIPTION
The other operational amplifier, combined with few external resistors and the voltage reference, can be used as a current limiter. Figure 1. Pin
