DESCRIPTION

The TSM1011 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes.

The TSM1011 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.

■ Constant voltage and constant current control

■ Low voltage operation

■ Low external component count

■ Current sink output stage

■ Easy compensation

■ 2KV ESD protection

■ VOLTAGE REFERENCE:

• Fixed output voltage reference 2.545V

• 0.5 and 1 voltage precision

APPLICATIONS

■ Adapters

■ Battery chargers

TSM1011IS属于集成电路（IC） > 电压基准。意法半导体（ST）集团制造生产的TSM1011IS电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
