Description

The NE5561/SE5561 is a control circuit for use in switched-mode power supplies. It contains an internal temperature- compensated supply, PWM, sawtooth oscillator, overcurrent sense latch, and output stage. The NE5561/SE5561 is intended for low cost SMPS applications where extensive housekeeping functions are not required.
