Part Number: UCC28951-Q1 Other Parts Discussed in Thread: UCC28950-Q1 , UCC2895-Q1 , UCC28951 Hello
Can I use UCC28951-Q1 for larger input voltage range ( 310 Vdc to 410 Vdc ) for developing DC-DC converter ?
If not what is the range of input voltage…
Hello Swaminath, Interesting application
At this power level you must start with a PFC power factor correction creating a ~400V DC buss. Follow it with an isolated converter that can allow it's Vout to vary by duty cycle control. PFC: There are several…
Hi,
Thank you for the info.
I saw the UCC2895 EVM User's guide, as you said , UCC2895 is placed in primary side,
but using the CT for current sensing.
and I couldn't find the Ref design with using the sense resistor for current sensing on primary…
Other Parts Discussed in Thread: UCC2895 , UCC28950 Hello,
i want to design an inverter with 25 to 50V DC input and 250Vrms pure sinewave output with flyback topology with unfolding bridge . The output of flyback should be rectified sinewave. Can i…
Other Parts Discussed in Thread: UCC3895 , UCC2895 The UCC3895 has a minimum operating temperature of 0C. We've had multiple failures of the IC when the temperature is 5C or less. No problems at >5C. My question is why the operating spec of 0C? Should…
Other Parts Discussed in Thread: UCC28950 , UCC3895 , UCC2895 Dear TI engineer
I've tested my 3kW DC-DC converter with your ucc28950 PWM IC.
However, currently I have unanymous problem.
At light load condition, Output C/D duty was not 50 to 50%…
Other Parts Discussed in Thread: UCC2895 I got the Reliability Data: DPPM / MTBF / FIT Rate from ESP for UCC2895. Would like to know what is the main failure mechanism and life expectancy.
Thanks.
