Self-Supplied Monolithic Switcher for Low StandbyPower Offline SMPS
NCP1010, NCP1011, NCP1012, NCP1013, NCP1014
The NCP101X series integrates a fixed−frequency current−mode controller and a 700 V
MOSFET.
Housed in a PDIP−7 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).
