Self-Supplied Monolithic
Switcher for Low StandbyPower 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).
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.
