Part Number: LM25180-Q1 Other Parts Discussed in Thread: LM25180 Tool/software: Hi Team,
During EMI RE evaluation on customer's board, there is an issue that doesn't pass RE test condition in 300MHz to 500MHz band. Could you recommend how to improve or…
Part Number: LM25180-Q1 Tool/software: Hi team,
1. May I ask the maximum duty cycle of LM25180-Q1?
2. In BCM mode, as power increases, the switching frequency decreases. What is the minimum frequency in this mode?
3. For the problem of sub-harmonic oscillation…
Part Number: LM25180-Q1 Tool/software: there is obvious ringings when MOS is off, as shown in below picture, the ringing almost touches 0V. As it's a primary-side regulated (PSR) flyback converter, will this almost reaching 0V ringing cause MOS be mis…
Part Number: LM25180-Q1 Tool/software: Hi TI team,
There is no Aux widing, but to improve the customer board, the customer is reviewing the data sheet's application.
The circuit of the application is output 24V / 5V.
However, in the Flyback Transformer…
