LM26480: Power Management IC - Low noise

Mohamed Aashik S
Prodigy 95 points
Part Number: LM26480
Other Parts Discussed in Thread: TPS65050

Tool/software:

Hi, 
I need a Power Management IC with 4 LDO's in it. 
The requirements are

1. Each LDO should have individual EN pins

2. Each LDO output should be hardware configurable. It should have individual Feedback pins. 

Voltage range: 
Vin: 1V to 15V

Vout: 1.5V to 5V

Iout: 6A

Please suggest a very low noise Power Management IC for this end application.

    Hi, 

    Thank you for your interest in TI PMICs. 

    From the TPS6505x  device family, the TPS65051, TPS65054, and TPS65056 would best fit your needs.

    •  4 externally adjustable LDOs with resistor dividers at their feedback pins. 
    • Each LDO has its own EN pin
    • VIN: 1.5 V to 6.5 V
    • VOUT: 1 V to 3.6 V

    LDOs generally cannot support high current.
    VLDO1 & 2 can support up to 400 mA. VLDO3 & 4 can support up to 200 mA.
    This device does have 2 additional buck converters that can be used.

    For higher current up to 6A, a buck would need to be used. 

    Please take a look at the device family, and see if it fits your needs.
    The datasheet may be confusing to navigate, since TPS65050 and TPS65052 share the same datasheet, but do not have the externally adjustable LDOs.

    Let me know if you have any questions, or would like any other device recommendations!

    Best Regards,
    Sarah
