Part Number: UCC28056 The UCC28056 datasheet and XLS design tool set the Kzc voltage division ratio to 401 by default. Is this the internal default or recommended value of the chip? If my input voltage ranges from 176 to 256 V, can I change this ratio…
Part Number: TMS320F280049C
Dear TI Technical Experts,
I plan to develop a programmable DC power supply with the following key specifications:
Output voltage: 0~20 V DC
Output current: 0~200 A
Rated output power: 4000 W
Input power: compatible with…
Thank you very much for your previous response. I will revise and further optimize my PCB design in accordance with your suggestions.
Meanwhile, for the purpose of systematic performance evaluation and characterization of the designed 1-GHz-class…
感谢您的回复，再TRM里面找到这段话，
The input supply of DCDC can range from 2.2V to 3.8V. DCDC regulates the output to 1.5V. But for GLDO, the
supply can range from 1.71V to 3.8V to generate a regulated output of 1.5V. DCDC hardware is designed so
that when the supply…
Part Number: LM139A Other Parts Discussed in Thread: LM239 , LM339 , LM2901B , LM339B , LM2901 Dear Madam/Sir,
For LM139AD, there have 3 questions from my side:
What is the output of LM139AD when input voltage higher than 30V&36V or lower than 2V? If it will…

Part Number: UCC28C56EVM-066 Hi Team, I am currently designing a wide input voltage range DC‑DC converter using the UCC28C56. For reference, I have been reviewing the UCC28C56EVM circuit. Could you please clarify whether the same calculations or design template…
Part Number: OPA858 Dear Engineer,
I would like to ask a technical question regarding the OPA858DSGEVM board I purchased earlier.
At first, the board did not work when I applied a signal to the inverting input. After reviewing the schematic, I suspected…
Clarifications Needed
Before diving in, a few details from your posts would help refine this further:
When you say "driver loss," are the gate signals completely absent during portions of the cycle, or are they intermittent/degraded in amplitude…
Part Number: DAC7612 We are facing an issue: how to quickly tell whether DAC7612U or DAC7612UB is mounted on our products. Our end customers have questioned how we can confirm that DAC7612UB, rather than DAC7612U, is used on the units. According to the…
