TS103ACS RLG

P1-P3P4-P6
TS103
Taiwan Semiconductor
1 Version: D1701
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
