LP87564-Q1: A4001 replacement

Part Number: LP87564-Q1
Other Parts Discussed in Thread: LP8758

Tool/software:

Hello expert,

Could you provide the replacement for A4001 from Aerosemi? I checked the spec from customer side and A4001 is 4-ch 4Apeak/ch PMIC. And the Vin is 2.7V to 5.5V. Customer's requirement is shown below. 

CH1 : 0.9V / CH2 : 1.2V / CH3 : 1.8V / CH4 : 3.3V. I'm asking for current but it should be lower than 2A per channel. Is LP87564-Q1 suitable for customer? If no, please kindly help to share your comment to us. Thanks a lot!

Best regards,

Ann Lien

    Hi Ann,

    Can you tell me what their VIN requirement is? Can they write to the device before enabling it? If the business case is big enough, we can generate a new spin with custom settings which this device or the LP8758 should be able to fulfill.

    I checked the spins that we have for this device, and there does not appear to be a specific match. We have a spin with 3.3V, 1.2V, 1V and 1.8V, but it may also have other undesired settings. So for an 4 buck only converter PMIC, and not being able to generate a custom spin, there may not be another suitable replacement, but I will look to see.

    Thanks,
    Field
