TSM1012 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
TSM1012 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and
CC (constant current) mode. TSM1012 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, combined with few external resistors and the voltage reference, can be used as a current limiter.
