The design specs are: Non isolated 18Vout, 10Vin min 14Vinmax, 12Vin nom, Vout 32-40V (anywhere in that range is fine since the circuit will have a variable linear post regulator, but that part is already figured out so the input voltage can vary by a…
Part Number: UCC38C43 Hello, The reference voltage inside the UCC38C43 controller is said to range between 4.9V to 5.1V. The internal error amplifier of the UCC38C43 is presumably supplied from this reference voltage, so how is it that near the bottom…
Part Number: UCC38C43 Hello friends,
I was wondering if anyone can help come up with the appropriate TI parts to design a simple Buck Boost using the UCC38C43.
input : 12 to 30 VDC
Output: 0 to10 Amps
3 segment display with a divide by 10 switch…
Since there has been no activity for a while no on this post, I hope you have resolved the problem. Please open a new post if you need more help.

Other Parts Discussed in Thread: UCC38C43 Hello,
I'm looking for help selecting a suitable online AC-DC converter solution.
In this application we are taking a phase-cut 120VAC input and need to step it down to a fixed 12 - 24 VDC. Because of the…
Part Number: UCC2813-2 Other Parts Discussed in Thread: UCC38C43
With a large output Capacitance, can hiccup current limiting be avoided during start up with the UCC2813 device? Using the UCC38C43 part, it takes approx 12ms to rise from 0V to regulation…

Hi Peter,
Alternative part UCC38C43 is current mode controller, but UCC25705D is voltage mode controller. Can you please clarify how spice model of UCC38C43 will help for UCC25705D based design?
Thanks,
Jeyaprakash K
