Part Number: UCC25705 Other Parts Discussed in Thread: UCC38C42 ,
Hello Support team,
Could you tell me how UCC25705 support external clock synchronization? I find application example in SLUA257 for UCC38C42 case. Can UCC25705 support with same method…
Bogdan,
Thanks for your interest in TI here.
The turns ratio and inductance are calculated in section 9.2.2.2 and 9.2.2.3 on pages 23 and 24.
Alternatively you could use Webench to calculate your design from the product folder here:
Additionally you…
Part Number: UCC28C44 Other Parts Discussed in Thread: UCC38C42
Hello guys,
One of our customer is evaluating UCC28C44 on their own AC/DC converter which generates 24V/6A DC from 115V AC input. When their AC/DC converter operates with light loard, burst…
Thanks Peter,
That looks like an option! I however cannot seem to figure out what the input range/gain is on the FB pin. I would imagine it would only need a small change to go from 0-100% PWM which is not ideal for my (repurposed) application. I'm thinking…
Part Number: UCC28C42
Tool/software:
Hello,
In the new and updated datasheet of UCCx8C4x (REV I) a new line of COMP Pin sourcing current when FB pin shorted is added and current = 5.5mA max.
1. Why the new behaviour?
2. Was it ways like it or something…
The PSR controllers with integrated power switch like the UCC2910 family and the PSR controllers with high voltage start up like the UCC28710 family all require a minimum of 35V input in order to start.
The UCC28700 PSR controller does not have an…
you should be fine using the same technique as that recommended for the UCC38C42. You should refer to U-111 (SLUA110) for several "practical considerations" for current mode power supplies. Soft start isbreifly discussed on page 3-117.
Other Parts Discussed in Thread: UC3843 , UCC38C43 , UCC38C42 Is there a device very similar or identical to the UC3843 but has soft start circuitry included?
Cheers
Calum
