SelfSupplied 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.
