Other Parts Discussed in Thread: LM5143,
Dear All,
Here are 2 outputs that I'm trying to achieve:
Output I
- Input voltage: 46-54V
- Output voltage: 12V +/-5%
- TDP: 250W (30A)
- OCP: 50A
- Type: non isolated
- Ambient: 60C
- Cooling: ?
- Enable: required.
Output II (optional)
- Input voltage: 46-54V
- Output voltage: 3.3V +/-5%
- TDC: 3A
- OCP: 10A
- Type: non isolated
- Ambient: 60C
- Cooling: ?
- Enable: required.
I found out that the LM5140 supporting these 2 output but with relative low efficiency (86.1% with 30A).
Is there any other device with higher efficiency at 30A load that can support 2 outputs?
is there any way we can improve the device efficiency?
best regards.
