KA7511
SMPS Controller
Features
• • • • Wide Operating Range Under
Voltage Lockout Direct Switching TR Drive Low Start-Up Current
Description
The KA7511 drives, regulates and monitors the main switching element in a SMPS based on the nonsynchronous flyback theory.
Because of the wide regulating range and the high
voltage stability during large load changes, the power supplies for TV receivers and video recorders can be realized.
