Hi Expert,

Customer is seeking a PMIC, which DCDC output voltage is 3.3V & 5V, output current is 1A. While I find TPS653860-Q1 DCDC's min output voltage is 4.3V. Could you help check if DCDC can meet the 3.3V output requirement?

Hi Beida,

We have many DCDCs capable to output 3.3V and 5V but what is required input voltage range and are there any other outputs needed than 3.3V and 5.0V? Any functional safety requirements?

Hi Jari,

Customer needs a PMIC. 3.3V output is a requirement of DCDC. So TPS653860-Q1 can support this? If not, how about TPS650362-Q1?

Hi Beida,

TPS653860-Q1 can only support listed fixed options 4.3 V, 5.0 V 6.0 V and 6.8 V.

TPS650362-Q1 output is more flexible and can be programmed from 3.0 V to 5.5 V.

What is your VIN range? Any other outputs needed than 3.3 V?
