Data Sheet
QUAD OP AMP AND VOLTAGE REFERENCE
General Description
Features
AP4303
The AP4303 is a monolithic IC that contains quad
operational amplifiers and a precision shunt regulator,
1.25Vfor AP4303-C or 1.24V for AP4303-D respec-
tively. It is specifically designed to regulate the output
current and voltage levels of switching battery charg-
ers and power supplies.
The four Op Amps feature accurate voltage and current
control. Combining a stable voltage reference with the
four Op Amps makes AP4303 ideal for use in multi-
function charger, power supply voltage monitor, signal
processing and control system.
The IC offers the power converter designer a control
solution that features increased precision with a corre-
sponding reduction in system complexity and cost.
