TPS61230: DC/DC Output Voltage 3.3V, 4.2V (2A) , 5V (2A)

Part Number: TPS61230
Other Parts Discussed in Thread: BQ25895,

Hello,

I use a BQ25895 charger chip with a 18650 lipo to supply different chips in a portable device. I used different dc/dc converters to get the different supply voltages. Is there any other chip, which can handly this different voltages better?

  • Reader: 3.2-5.25V, 8W (5V @ 1.6A)
    • DC/DC @ Vsys: PTN04050CAH (5V, 2.4A)
  • GSM: 3.4-4.4V, (2A in Burst Mode for a short time)
    • DC/DC @ Vsys: TPS61230DRCD (4.2V, 2.1A)
  • GPS: 3.3V, (100mA)
    • LDO @ 5V

Thanks Andi
