Self--Supplied Monolithic
Switcher for Low Standby--
Power Offline SMPS
The NCP101X series integrates a fixed--frequency current--mode
controller and a 700 V MOSFET. Housed in a PDIP--7,
PDIP--7 Gull Wing, or SOT--223 package, the NCP101X offers
everything needed to build a rugged and low--cost power supply,
including soft--start, frequency jittering, short--circuit protection,
skip--cycle, a maximum peak current setpoint and a Dynamic
Self--Supply (no need for an auxiliary winding).
Unlike other monolithic solutions, the NCP101X is quiet by nature:
during nominal load operation, the part switches at one of the available
frequencies (65 -- 100 -- 130 kHz). When the current setpoint falls
below a given value, e.g. the output power demand diminishes, the IC
automatically enters the so--called skip--cycle mode and provides
excellent efficiency at light loads. Because this occurs at typically 1/4
of the maximum peak value, no acoustic noise takes place. As a result,
standby power is reduced to the minimum without acoustic noise
generation.
Short--circuit detection takes place when the feedback signal fades
away, e.g. in true short--circuit conditions or in broken Optocoupler
cases. External disabling is easily done either simply by pulling the
feedback pin down or latching it to ground through an inexpensive
SCR for complete latched--off. Finally soft--start and frequency
jittering further ease the designer task to quickly develop low--cost and
robust offline power supplies.
For improved standby performance, the connection of an auxiliary
winding stops the DSS operation and helps to consume less than
100 mW at high line. In this mode, a built--in latched overvoltage
protection prevents from lethal voltage runaways in case the
Optocoupler would brake. These devices are available in economical
8--pin dual--in--line and 4--pin SOT--223 packages.
