major leap toward ultra- -compact Switchmode Power Supplies and
represents an excellent candidate to replace the UC384X devices. Due
to its proprietary SMARTMOS Very High Voltage Technology, the
circuit allows the implementation of complete off- -line AC- -DC
adapters, battery charger and a high- -power SMPS with few external
components.
100 kHz switching frequency, the controller features a high- -voltage
startup FET which ensures a clean and loss- -less startup sequence. Its
current- -mode control naturally provides good audio- -susceptibility
and inherent pulse- -by- -pulse control.
power demand diminishes, the IC automatically enters the so- -called
skip cycle mode and provides improved efficiency at light loads
while offering excellent performance in standby conditions. Because
this occurs at a user adjustable low peak current, no acoustic noise
takes place.
in presence of an output over load condition, disables the output
pulses while the device enters a safe burst mode, trying to restart.
Once the default has gone, the device auto- -recovers. Finally, a
temperature shutdown with hysteresis helps building safe and robust
power supplies.
