Adaptive synchronous rectifier controller in 6pin SOT23

ST has introduced a pair of autonomous secondary-side synchronous-rectification controllers for fly-back converters, suitable for quasi-resonant and continuous-discontinuous conduction fixed frequency circuits up to 300kHz. Called SRK1000A and SRK1000B, they include adaptive switching logic “such that the synchronous rectifier mosfet is switched on as soon as current starts flowing through its body diode and it is then switched ...

O-S-D sales to fall 6%

After 10 years of record-high sales, combined revenues for optoelectronics, sensors/actuators, and discrete semiconductors are expected to drop 6% in 2020, says the O-S-D Report from IC Insights. When 2020 began, global conditions pointed to single-digit percentage market growth this year for O-S-D devices, but the outlook suddenly deteriorated in Q1 due to the coronavirus. ...
