NCP1015
Self-Supplied Monolithic
Switcher for Low Standby-
Power Offline SMPS
The NCP1015 integrates a fixed ? frequency current ? mode
controller and a 700 V voltage MOSFET. Housed in a PDIP ? 7 or
SOT ? 223 package, the NCP1015 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 set ? point and a Dynamic Self ? Supply (no need for an auxiliary
winding).

MARKING
DIAGRAMS
Unlike other monolithic solutions, the NCP1015 is quiet by nature:
during nominal load operation, the part switches at one of the available
frequencies (65 ? 100 kHz). When the current set ? point 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 0.25
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. un ? true short ? circuit or is broken optocoupler cases. 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.
