TPS55010: Low Iq isolated DC-DC

Part Number: TPS55010

Hello, I'm looking to develop an isolated DC-DC with input of 3.3V and output of 12V with a maximum output current of 50 mA. The main consideration of this is low standby current drawn from input without any load on output - less than 500 uA.

Would this be possible with TPS55010 or do I need to use any other chipset?

  • Hi Prithvi,

    Thanks for using E2E.

    The TPS55010 is the correct device for your requirements. You can use the WEBENCH tool on ti.com for the schematic and simulation:
