1377B - Brand New ON Semiconductor IC Chips
-
Description
The Electronic Component Model 1377B is an IC chip commonly used in various electronic devices. It features a combination of a true current mode modulator and a demagnetization detector, ensuring full borderline/critical Conduction Mode in any load/line conditions with minimum drain voltage switching. The controller also has a skip cycle capability, entering burst mode when the power demand falls below a predetermined level, resulting in no audible noise. The NCP1377 has an internal 8.0 s timer to limit the frequency below the CISPR-22 EMI starting limit of 150 kHz, while the NC1377B has a reduced internal timer duration of 3.0 s for operation at higher frequencies up to 300 kHz.
