Part Number: TPS54360B-Q1
Other Parts Discussed in Thread: LM76003-Q1, TPS54360B, LM76003

Hi Team,

I have a requirement for DC DC converter for automotive grade requirement,

DC DC converter will be driven through a vehicle battery, which is 12.6V [TYP]

Vin: 12V ~ 60V [Range]

Vout: 5V

Iout: 3.5A

I build a circuit through webench power design tool and found, "TPS54360BQDDARQ1 " this part. Please find the attached schematic for your reference.

Here is my clarification, am i selected the right part for my requirement ?

Do we have any other better solution to my requirement, where my circuit blocks are having below peripherals

GSM, GPS module, Micro Controller, 3.3V LDO, Battery Charger [4.2V], 3.8V GSM regulator, USB-Serial converter, RTCSCHEMATIC1 _ Power Block.pdf

Thanks,
Rahul

Hi Rahul,

Yes,you can use the TPS54360B-Q1 or maybe a newer part such as LM76003-Q1

http://www.ti.com/product/LM76003-Q1?keyMatch=LM76003-Q1&tisearch=Search-EN-everything&usecase=part-number

The newer part has more features in terms on synchronizable and adjustable soft-start time.

Thanks

Hi Arief,

Thanks for your comments. Before i start my design with TPS54360B I would need more layout guidelines to suppress the switching noise to not effecting my GPS and GSM module functional performance. Kindly share me the details for shielding mechanism / kind of method to avoid switching ground noise effecting entire PCB board. Which may finally effect for the performance of my GSM and GPS module.

Thanks,

Rahul

Hi Rahul,

I think in general either following the EVM layout or layout guidelines on the datasheet should be a good starting point.

The newer part LM76003 has integrated FET instead of diode, therefore the high di/dt loop is smaller and the location for the input capacitor is close to the IC

Thanks

Hi Arief,

Thanks, If you look in to my schematic, you can see the input EMI filter block. Please suggest me the suitable components [Proper filter element package & Part Number] to take care of the EMI noise suppression .

Thanks,

Rahul
