Description

IK3051 is a highly integrated solution for SMPS applications requiring constant voltage and constant current mode.

IK3051 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 other low voltage reference combined with the other operational amplifier makes it an ideal current limiter for output low side current sensing.

Features

• CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROL

• LOW VOLTAGE OPERATION

• PRECISION INTERNAL COMPONENT COUNT

• CURRENT SINK OUTPUT STAGE

• EASY COMPENSATION

• LOW AC MAINS VOLTAGE REJECTION
