SelfSupplied Monolithic
Switcher for Low Standby
Power Offline SMPS
The NCP101X series integrates a fixedfrequency currentmode
controller and a 700 V MOSFET. Housed in a PDIP7,
PDIP7 Gull Wing, or SOT223 package, the NCP101X offers
everything needed to build a rugged and lowcost power supply,
including softstart, frequency jittering, shortcircuit protection,
skipcycle, a maximum peak current setpoint and a Dynamic
SelfSupply (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 socalled skipcycle 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.
Shortcircuit detection takes place when the feedback signal fades
away, e.g. in true shortcircuit 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 latchedoff. Finally softstart and frequency
jittering further ease the designer task to quickly develop lowcost 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 builtin latched overvoltage
protection prevents from lethal voltage runaways in case the
Optocoupler would brake. These devices are available in economical
8pin dualinline and 4pin SOT223 packages.
