DLPC8445: Dlpc3082 built-in buck-switching regulators

Part Number: DLPC8445
Other Parts Discussed in Thread: DLPA3082

Tool/software:

Hello,

The DLPC3082 has three built-in buck-switching regulators, one of which has a fixed 0.8V output for DLP chipset core power. Could you please provide information on the internal resistor value of feedback divider network(ex: R1&R2) and the reference voltage(VREF)? Thank you.

    Hello User,

    Welcome back to the E2E forums and we look forward to assisting you with your questions.

    Please give our team some time to look into this request with the hardware team and we will get back to you shortly.

    Just for clarification you are referring to the buck-switching regulators mentioned here in the DLPA3082 datasheet?

    Regards,

    Alex Chan

    Hello User,

    Feedback from the hardware team is that we do not provide internal resistors or values.

    The remaining general purpose buck regulator setup can be seen as follows from figure 6-5 in the DLPA3082 datasheet with all the necessary peripheral circuitry.

    Regards,

    Alex Chan
