General Description
The TS103 is a monolithic IC specifically designed to control the output current and voltage levels of switch mode
battery chargers and power supplies.
The device contains two operational amplifiers and a precision shunt regulator. Op Amp 1 is designed for voltage
control, whose non-inverting input internally connects to the output of the shunt regulator. Op Amp 2 is for current
control with both inputs uncommitted. The IC offers the power converter designer a control solution that features
increased precision with a corresponding reduction in system complexity and cost.
