Hi E2E Team,
I am working on one AC- DC power supply development which has the requirement of AC I/P range is from 90-130VAC and O/P of 5V/50W.
we have a high efficiency (>90%) requirement…
Part Number: UCC2897 Hi
Customers can adjust RDEL from 4.99KΩ to 5.6KΩ and 10KΩ according to the Spec,
and the measurement waveform is as attached It is found that when the Q14/Q19 is adjusted to 10K,
there is no signal to turn it…
Part Number: UCC2897 Hi
RTPS-220C (100W) is revised to IRTPS-240 (120W), the output of IRTPS-220C UCC2897APW (U2) is now 12V/9A, the output voltage of IRTPS-240 is the same as 12V, and the output current needs to be increased to 11A, the attachment is…
