TS103ACS

Taiwan Semiconductor

1 Version: E2103

Dual Operational Amplifiers and Voltage Reference

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.

FEATURES

● Input Offset Voltage: 0.5mV

● Supply Current: 250μA per OP AMP @ 5V

● Unity Gain Bandwidth: 1MHz

● Output Voltage Swing: 0~(V
