DLPA200: VOFFSET/VCC2 filter capacitor

Part Number: DLPA200
Other Parts Discussed in Thread: DLPLCRC410EVM

Hi E2E support,

According to DLPA200 datasheet, a value of VOFFSET/VCC2 filter capacitor is 1-4.7µF.

Note : Recommended value is 3.3 µF each.

Different values are acceptable, provided that the sum of the two is 6.8 µF maximum.

However, 10uF filter capacitors are used for the DLPLCRC410EVM.

Which is correct ?

If the description of the datasheet is correct, why 10uF filter capacitors for the VOFFSET/VCC2 are used in the EVM board?

Best Regards,

Hello Koike,

We will review this item, but likely the data sheet is a refinement since the EVMs were first built.

Hello Koike-san,

Sorry for the delay. After consulting our board folks, they indicated that 10 µF is acceptable. We will review whether a data sheet update is in order.
