Monolithic switch low standby power offline
Series integrated RR controller
and. Housed in a stand, gull wing, or package,
Provides everything needed to build a rugged, durable power supply, including r, frequency jitter,
protection, maximum peak current setpoint and dynamics (no need for an auxiliary winding).
Unlike other monolithic solutions, nature is quiet: at rated load operation, the part switches at one of the available frequencies (kHz).
When the current setpoint drops below the given value, the output power Mode automatically enters as demand subsides,
and provides excellent efficiency at light loads.
Because this occurs at the top of the usual peak value, no noise occurs. Therefore, standby power is reduced to a minimum noiseless generation.
Detection occurs when the feedback signal disappears far under real
conditions or in the case of a broken optocoupler.
External disabling or simply is easy to do by pulling the feedback pin or latch it through a An inexpensive ground complete R.
Last r and frequency dithering further simplify the design task and quickly develop powerful off-line power supplies.
To improve standby performance, an auxiliary connection winding stops operating to assist under consumption of high line. In this mode,
Overvoltage lockout protection prevents the optocoupler from fatally braking under high voltage conditions.
These devices are available in economical and package
