Question about DLPA3000

Other Parts Discussed in Thread: DLPA3000

Hi all.

we have one question for DLPA3000.

When choosing an inductor and Capacitor (Cin/Cout), there is no necessary design policy.

Ipk? L Value_minimum? Irms? Cin/Cout vs Vripple? possible to use Ceramic Cap for Cin/Cout?

It's possible to make the inductor of EVB reference, But we can't judge we have enough room for derating.

Hi cronos,

For the LED driver regulator, the component selection and design info is in section 7.3.2.3, page 22-24, of the DLPA3000 Datasheet.

For the other buck regulators, the component selection and design info is in section 7.3.4.2, page 37, of the DLPA3000 Datasheet.

Selection of specifc inductor brand or type is up to customer.

Regards,
