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,

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

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

DSS Internal Dissipation
The Dynamic Self−Supplied pulls energy out from the
drain pin. In Flyback−based converters, this drain level can
easily go above 600 V peak and thus increase the stress on the
DSS startup source. However, the drain voltage evolves with
time and its period is small compared to that of the DSS. As
a result, the averaged dissipation, excluding capacitive losses,
can be derived by: PDSS + ICC1 · t Vds(t) u . (eq. 4) .
