Part Number: UCC28C43 Hi,
Currently, we are planning to construct a circuit using UCC28C43 and LDO to develop a power supply module. LDO is used to lower the voltage from -24V to satisfy the power supply voltage range of UCC28C43.
Could you tell me…

Yes , we do have 2ohm sense resistor . This is because we do not want to increase…
Part Number: UCC28C43 Our EMS manufacturer has asked us to confirm whether the UCC28C43 used in our circuit is compatible with devices manufactured in Mexico and Malaysia.
Could you please advise if there are any differences between products from these…
Hi Asha,
John Gomez said: Sense resistor was reduced to 400mohm , around 258mV ripple is observed when ~100mA loaded on 15V. Blue represents output voltage ripple and yellow represents comp pin voltage in the below waveform. Also we observe overshoot…

Hi UCC28C43 support team,
I'm using a UCC28C43DR to construct a DC/DC power supply circuit (150V input, 12V output isolated flyback converter) as shown in Figure 8-3. https://www.ti.com/lit/ds/symlink/ucc28c43.pdf#page=26
Is…
Part Number: UCC28C43 I'm designing an asynchronous CCM-mode buck converter. The specifications are: input voltage 300 V and output voltage 28 V, so the duty cycle is 9.3% and Pout = 37 W. The operating frequency could be 100 kHz or 200 kHz. The gate…

Part Number: UCC28C43 Tool/software: Hi engineers,
I’m working on a high-frequency push-pull converter using the UCC28C43 PWM controller, targeting around 100kHz operation for a compact power supply. I noticed that the MOSFETs are getting unusually…
Part Number: UCC28C43-EP Other Parts Discussed in Thread: UCC28C43 Hello,
We are using UCC28C43 controller for flyback design.
Input voltage - 180V to 320V
Output voltage - 15V
We are using type ii compensation circuit here,
At 320V ,…
