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: 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…
Part Number: LM25180-Q1 Tool/software: Hi TI team,
My customer made the board and started the functional test.
But the board doesn't work, so please review the schematic.
The auxiliary winding is designed to output 5.7V from the primary side.
Q1…
