DESCRIPTION
The NE/SE5560 is a control circuit for use in switched-mode power
supplies. This single monolithic chip incorporates all the control and
housekeeping (protection) functions required in switched-mode
power supplies, including an internal temperature-compensated
reference source, internal Zener references, sawtooth generator,
pulse-width modulator, output stage and various protection circuits.
FEATURES
