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.
