Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software: I want to design wide input range buck converter.
Specifications are as follows:
Vin_min = 14.4 Vdc
Vin_max = 154 Vdc
Vout =12Vdc
Iout =1A
I don’t want to use…
Part Number: UCC28C43-Q1 UCC28C43QDRQ1's datasheet suggests that the RT resistance should be configured above 1kΩ.
However,we have using the RT/CT combination of 820R/1nF to produce a square wave with a duty cycle of 50% at 1MHz.
I hope to confirm…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software: Hi team,
My customer Valeo are using UCC28C43 for their HVLV flyback circuit.
They performed the simulation, the Idd of UCC28C43 reached about 4mA during starting up…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software: Hello Folks,
We are using the UCC28C43 device in a flyback application in our product and we have noticed that for a high input voltage and typical load, the controller…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software:
current sense gain from the UCC28C43 datasheet is typ 3V, but in the IC block diagram gain section did not shown, CS pin input is directly going to the PWM comparator…
Part Number: UCC28C43-Q1 Tool/software: Hi E2E,
We are designing a power supply using UCC28C43-Q1.
In previous designs,the negative feedback input to the COMP is after optocoupler isolation .
We want to know if there is a way to directly feed the…
Part Number: UCC28C43-Q1 Other Parts Discussed in Thread: UCC28C43 Tool/software: Hello Team,
I'm using the UCC28C43 as the flyback controller (DCM operation). I have designed a startup circuit to supply the controller intially. This will supply until…
Part Number: UCC28C43-Q1 Dear TI team,
I am using UCC28C43-Q1 IC for my Flyback converter application. I want to implement Enable/ Disable signal to Flyback converter.
In datasheet, it shows only MOSFET and Disable signal from micro-controller…
Part Number: UCC28C43-Q1 Hello,
I am looking for some support using the COMP pin to disable the PWM IC. I use the P-MOSFET to pull COMP to GND as suggested in the datasheet. The voltage of COMP initially stabilized at 3.38V. Then P-MOSFET is turned…
Part Number: UCC28C43-Q1 Hello colleagues,
My customer has an issue with UCC28C43-Q1, t he controller is part of a flyback converter, as shown in the following picture:
The voltage of the Aux winding is regulated.
During stability studies, we…
