TSM1012 is a low power voltage and current controller for battery chargers and adaptors. It integrates one 1.25V fixed output voltage reference and two switch mode operational amplifiers to realize both constant voltage and constant current control.
The TSM1012 is a highly integrated solution designed for SMPS applications requiring constant voltage (CV) and constant current (CC) control. It integrates a voltage reference and two operational amplifiers with ORed outputs to function as a voltage controller and a current limiter. The device is suitable for use in adapters and battery chargers, operating with a supply voltage range of 4.5V to 28V and temperatures from -40°C to 105°C.
