Part Number: UCC28180 Hello,
I try to obtain a 800V output with 400W DC/DC converter. The output load is just a 133uF capacitor. So, 400W output power comes from just charging and discharging this capacitor between 800V and 0V. I shared the circuit…
Part Number: UCC28180 Hello Experts ,
I am working on 650W PFC based on UCC28180 . Need help to understand what happen if ISENSE pin Diode is BAT54HT1G , Current sense resistor =15 mohm , Rsense = 220 Ohm . Is BAT 54HT1G is wrong choice ? is this cause…
Part Number: UCC28180 Hi TI Team,
I am using the UCC28180 in a CCM PFC design. I added a 300-ohm resistor(DR262) as a voltage‑divider element before ISENSE (pin 3) to attenuate the shunt‑voltage. The purpose is to effectively raise the OCP current threshold…
Part Number: UCC28180 Other Parts Discussed in Thread: UCC28056 Hello.
I plan to design a PFC boost converter. I wonder if UCC28180 is the correct one for this use. Can you verify it can be used for my project? Are there better options for high output…
Part Number: UCC28180 Dear Team,
We are currently using the UCC28180 PFC controller for one of our applications. The design is intended for a 230V AC (50 Hz) input , generating approximately 400V DC output using a Boost PFC topology.
We would like…
Part Number: UCC28180 Other Parts Discussed in Thread: UCC28070 Dear TI,
input single phase 230Ac 50Hz , We want to use (analog) PFC IC for 4.5kW solution so can we use UCC28180 , if no then please suggest if any other.
Part Number: UCC28180 Hello
We are developing a SMPS that requires strict primary side regulation.
We are evaluating the UCC28180 right now and its working well up to 650W witch is OK for our application.
The only issue we are facing is the OVP…
Part Number: UCC28180 Other Parts Discussed in Thread: LM5045 Dear TI team
I have designed a boost PFC circuit using Texas Instruments Webench with an input voltage range of 85–265 V and an output specification of 390 V, 1.15 A. However, I noticed that…
Part Number: UCC28180 Hello,
I am currently designing a rectifier, implementing power factor correction using the UCC28180 IC. The system requirements are as below:
Input: 230VAC, 50Hz
Output: 355VDC, up to 1.5kW max
At lower power up to 900W…
Part Number: UCC28180 Hi,
Based on the support team's recommendation, the inductance was doubled, but the results show the input current is still distorted, as shown in the figure below. I cannot overcome this by adjusting the inductor value. The current…
