Part Number: UC1825A Tool/software: Hi All,
I'm currently evaluating whether a negative transient (with a duration of approximately 1 ms) on the Vcc and Vc pins of part number UC1825A is enough to damage it. Is there a maximum allowed negative voltage…
Hey Hisui,
Correct. The UC1825A is electrically similar to the 5962-8768102EA and can be used to verify electrical functionality is a circuit before using the 5962-8768102EA.
Thanks,
Daniel
Part Number: UC1825A Hi,
Question regarding the Clock signal on Pin 4. We use this clock signal to trigger another external circuit. The loading current is about 3.7mA. UC1825A spec has maximum current of 5mA. Is there any issue if we are loading at…
Part Number: UC1825A Hello,
I have question regarding the 5.1V reference voltage. Beside initial tolerance, temperature variation and radiation effect, is this 5.1V will change due to aging effect ? Is there some data or equation to calculate this…
Part Number: UC1825A Hi TI Support,
I am looking for more detail information regarding the UC1825A (5962-8768012V2A) Error Amplifier parameters variation (Vio, Iio, Ibias).
1) Input offset voltage is listed as 2mV nominal and 10mV max. Is this variation…
Part Number: UC1825A-SP Hello,
Question about the UVLO threshold for the UC1825A-SP. The spec is about 9.2V nominal. What is the coefficient of this threshold over temperature ? Is it increase or decrease with Hot temperature ?
Best Regards,
Jason…
Part Number: UC1825A-SP If the Error Amp Out pin (Pin 3) is clamped at 2.5V as a secondary protection circuit beside the normal current limit (Pin 9). When the converter going into current limit, will the Clamp voltage at E/A OUT will override the Current…
Part Number: UC1825A Other Parts Discussed in Thread: UC1825 , UC1823 Do we have a chart comparable to Figure 3 of the datasheet for the 50% duty-max devices?
If not, do we have a a formula we can use that properly combines any delays & discharge times…
