NTE7109
Integrated Circuit
Switching Regulator Control
Description:
The NTE7109 is a primary switching regulator controller in a 16鈥揕ead DIP type package designed
to get the regulated DC voltage from an AC power supply. This device can directly drive a MOSFET
with fast rise and fall output pulses.
The NTE7109 contains not only a high frequency OSC and fast output drive, but also a current limiter
with fast response and high sensibility so a true 鈥渇ast switching regulator鈥?can be realized. By adding
additional compenents to the primary side, a timer鈥搕ype protection circuit can be made for protection
against short鈥揷ircuit and overcurrent.
