11.23. NCP1014
11.23.1. General
Description
The NCP101X series integrates a fixed
í
frequency current
í
modecontroller and a 700 V MOSFET.
Housed in a PDIP
í
7 or SOT
í
223package, the NCP101X offers everything needed to build a rugged
and low
í
cost power supply, including soft
í
start, frequency jittering, short
í
circuit protection, skip
í
cycle,
a maximum peak current setpoint and a Dynamic Self
í
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
í
100
í
130 kHz). When the current setpoint falls below a
given value, e.g. the output power demand diminishes, the IC automatically enters the so
í
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
í
circuit detection takes place when the feedback
signal fades away, e.g. in true short
í
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
í
off. Finally soft
í
start and frequency jittering further ease the
designer task to quickly develop low
í
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 than100 mW at high line. In this mode, a built
í
in latched overvoltage protection prevents from
lethal voltage runaways in case the Optocoupler would brake.
