TSM1052

The TSM1052 is a Constant Voltage and Constant Current Controller for battery chargers and adapters. This is a highly integrated solution for SMPS applications requiring a dual control loop to perform CV and CC regulation. The voltage reference, along with one op amp, is the core of the voltage control loop and the current sensing circuit and the other op amp make up the current control loop.

• Secondary-side constant voltage and constant current control
• Very low voltage operation
• Very low quiescent consumption
• High-accuracy internal reference
• Low external component count
• Wired-or open-drain output stage
• Easy frequency compensation
