TPS6521905: PMIC for FPGA and Controller Applications

Part Number: TPS6521905

Tool/software:

Dear Technical Support Team,

My customer is currently evaluating PMICs for use in a system that includes a Microchip PolarFire FPGA and a controller. We are looking for a power management IC that meets the following requirements:

Input voltage: ~5.5V
Output:
- Voltage range: 1V to 3.4V
- Number of outputs: At least 3 ports
Power sequencing
Simple voltage configuration: Ideally via external resistors or similar methods.
No dependency on external communication at startup

We found several products on your website that appear to meet these criteria. To help us narrow down the options, could you please recommend the most suitable products for our use case?

Please note that the required number of LDO outputs is still undecided at this stage.

Best regards,
Komatsuda

Hello Komatsuda-san,

Looking at your requirements,
I would suggest either of the following

TPS650250:

VIN: 2.5-6 V
3 Buck converters, 3 LDOs
All externally adjustable with resistor dividers
Separate enable pins for sequencing

TPS65053-Q1:

VIN: 2.5 - 6 V (bucks), 1.5 - 6.5 V (LDOs)
2 Buck converters, 3 LDOs
Bucks and two LDOs adjustable with resistor dividers, LDO3 fixed at 1.3V
Separate enable pins for sequencing

Let me know if you have any further questions about the devices above,
or if you would like more recommendations when you have a specific number of Bucks/LDOs in mind.

Best Regards,
Sarah
