Tool/software:

In one of our project power section requirements of 6–36V input with a 12V output at 2A load. For this purpose, we need a suitable buck-boost converter. Based on our analysis, we have identified the following two parts:

1. TPS55340-Q1 SEPIC

2. TPS55287-Q1 Buck-Boost

Could you please suggest the best part for our requirements in automotive and functional safety enable category?

Hi Rakesh,

Thanks for reaching out.

From the operation conditions, TPS552892-Q1(no I2C) is more suitable with 8A average inductor current limit. And Buck-boost solutions has better efficiency, less external components, smaller solution size, thus is more recommended.

	Buck-Boost	SEPIC
Ext. MOS	N/A	1 pcs
Ext. Diode	N/A	1 pcs
Ext. Inductor	1 pcs	2 pcs
Ext. Series cap	N/A	1 pcs

BRs,
