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 device is intended for low cost SMPS applications
where extensive housekeeping functions are not required.
FEATURES
Micro-miniature (D) package
Pulse-width modulator
Current limiting (cycle-by-cycle)
Sawtooth generator
Stabilized power supply
Double pulse protection
Internal temperature-compensated reference
