Part Number: UCC24630 We are doing 65W ,5V output flyback for universal input range . The switching frequency is 65kHZ, transfomer ratio 6.4:1 ,Inductance is 92uH.
For calculations of resistors i have used the UCC24630 design tool.Attached the Xl sheet…
Part Number: UCC24630 Hello.
I have a question about UCC24630.
Datasheet P5 VDRVST DRV pull-down in start-up
I have a question about pull-down.
1 It is supposed to work at start-up. Does it function even when it is stopped?(VDD = voltage below UVLO) 2…
Part Number: UCC24624 Other Parts Discussed in Thread: UCC24630 , UCC24610 , , UCC28950 , UCC2895 Hi,
i want to use this IC in my project but it has recommended voltage of 200V (absolute: 230V). i my application voltage drop across Vds-MOSFET would be 210V…
Ishii-san,
Apologies for the delay.
The only specs that are available are the ones already listed in the datasheet.
But as noted above, the Abs Max specs are continuous DC ratings, but the transient charge/discharge currents are much higher, as you…
Part Number: UCC24630 Other Parts Discussed in Thread: UCC28730 , UCC24610 , UCC24650 , , UCC24636 Hello, customer wants to use the UCC28730+UCC24650 and the UCC24630. I saw that the UCC24610 has an enable pin which can be connected to the the UCC24650 but…
Part Number: UCC24630 Other Parts Discussed in Thread: UCC28600 , We are designing a flyback power supply of 40W using UCC28600. We are using UCC24630 as the synchronous IC for the same. We have observed that our flyback IC is going to burst mode in case…
Part Number: UCC24630 Other Parts Discussed in Thread: UCC24636 Hi there,
I saw a reference design with 19.5V output/ 3A. Does TI have reference design for 5V 6A with up to 93% efficiency?
This is a very popular cellphone fast charger application.
Thanks…
Other Parts Discussed in Thread: UCC24630 Dear all
I have a flyback design using UCC24630 as secondary-side rectifier, which at startup shows a quick overshoot near 30V (vout nominal is 24V), a dangerous level for UCC24630.
I know I have to fix it in other…
Other Parts Discussed in Thread: UCC24630 , UCC24636 Hi, team,
Customer is developing an quasi-resonant fly-back power application using UCC24630.
UCC24630 was changed from UCC24636, because of same high current issue, about one month ago.
The high current…
