Part Number: LM25119 Other Parts Discussed in Thread: PMP20021 , PMP9700 Dear Sir,
DEMB(PIN17): floating is enable diode emulation mode and low side MOSFET latch-off. right ?
-> that mean LM25119 into like as non-sync. Buck converter during output light…
Hi Mike,
In my opinion, both MC34063A and UC3525 are not suitable for this high output current application, because they don't feature the synchronous function, which will cause a large power loss.
The reference design PMP10979 is closest to your requirement…
Sundy,
please look up PMP9700 TI Design with LM25119 for 300W output power; you can change the design per your specs.
