Part Number: UC2525B Hi Team
Customer encouter some issue when using UC2525B.
They add constant 5V in pin2, pin1 voltage changing from 1V-5V, but the output duty cycle didn't have any change.
They want to know why?
Other Parts Discussed in Thread: UC2525A , UC2525B , UC1525B , UC1525A I am comparing the UC2525A to the UC2525B. IN DN-36 the A has a cross conduction charge of 150 nC and the B has a cross conduction charge of 30 nC. When operating from 15V supplies…
Choi,
1. As highlighted in the datasheet difference between UC1525B (-55C to 125C ) and UC2525B ( -40C to 85C) is the temperature range. Parts are tested and guaranteed over the temp spec range.
2. UC1525B is only available in ceramic DIP package…
Hello Star
The waveforms of OUTA and OUTB look ok to me. I don't know where the other waveforms were taken from so I can't comment on them.
One thing that can happen with this IC is that noise on the I_lim/SD pin can disable OUTA or OUTB if it exceeds…
Hi Joe,
Please take the package drawing and the solder mask details from the following datasheet.
