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.
