TECHNICAL DATA
Constant Voltage and Constant Current Controller
for Adaptors and Battery Chargers
IK3051A
Description
IK3051A is a highly integrated solution for SMPS
applications requiring constant voltage and constant
current mode.
IK3051A integrates one voltage reference, two
operational amplifiers (with ORed outputs – common
collectors), and a current sensing circuit.
The voltage reference combined with one operational
amplifier makes it an ideal voltage controller, and the
www.DaottahSeheretl4oUw.comvoltage reference combined with the other
operational amplifier makes it an ideal current limiter for
output low side current sensing.
The current threshold is fixed and precise.
The only external components are:
• A resistor bridge to be connected to the output of
the power supply (adapter, battery charger) to set
the voltage regulation by dividing the desired output
voltage to match the internal voltage reference
value.
• A sense resistor having a value and allowable
dissipation power which need to be chosen
according to the internal voltage threshold.
• Optional compensation components (R and C).
IK3051A, is ideal for smallest package available, is
ideal for space shrinked applications such as adapters
and battery chargers.
