Part Number: LM3488
Other Parts Discussed in Thread: LM3478

Hi,

I can only find the datasheet of LM3488 from TI's website. The input voltage is 5V, and the output voltage is 400V/5mA.

1. Is there any reference design about LM3488?

2. Could you please provide scheme about the application (input voltage=5V, output voltage=400V, output current=5mA)?

Thanks.

Hi Kevin,

Attached is a reference design using the LM3478:
www.ti.com/.../PMP20212

The parameter differences between the LM3478 and LM3488 can be seen here:

You can use the reference design using the LM3478 as a start for your application. However, I think a good method would be to use a boost to charge pump configuration.

This may be helpful:

Best,
Richard
