Part Number: LM5015ISOEVAL Other Parts Discussed in Thread: LM5015NISOEVAL , LM5015 My customer wants use LM5015 and wants to refer layout of evaluation board. Please help to share the the design files or or Gerber Files of the LM5015ISOEVAL & LM5015NISOEVAL…
Yes, I'd like to know how the LM43600 handles the sync input internally. Which edge (rising or falling) is important, and what is the delay from that edge to switch turn-on, assuming 250 kHz operation. The LM43600 switch should turn on close in time to…
Part Number: LM5000 Other Parts Discussed in Thread: LM5015 , , LM5001 Hello All,
My customer is using the LM5000 in non-isolated flyback configuration, it would be possible to use in isolated configuration with opto-isolator feedback (for example,…

Hi Mahesh,
To answer two questions you had,
1. UCC28221 features a 2MHz capable oscillator. It should be able to handle 100kHz switching frequency.
2. Yes, UCC27211 works for half-bridge configuration. I've looked into it and it should also work…
Other Parts Discussed in Thread: LM5015 Hi,
I have a customer that has the following power supply: a symetrical one with voltage +/-60V. But he needs a symetrical supply +-15V , current rms=1A .
how could I generate that voltage from +-60 V power…
Jeff,
Yes you could configure the LM5033 as a sync buck. I have never done that, but let me know how it works. Have you looked at the LM5015, or the LM20323, these are both synchronous buck controllers.

Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
