Switched-mode power supply control circuit

NE/SE5561

DESCRIPTION

PIN CONFIGURATION

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 device is intended for low cost SMPS applications

where extensive housekeeping functions are not required.
