UCC28881: AC/DC selection for IoT, require power consumption <2mW at no load

Anderson Cheng

Part Number: UCC28881

Hello,

my customer have need a AC/DC chip, requirement as below:

1. input voltage 85Vac-265Vac.

2. output 6V

3. output power >1.5W

4. power consumption <2mW at no load.

5. efficiency when output power =15mW, input power consumption <=30mW.

6. temperature -40 to 150C

7. soft start

can you help to suggest which TI chip can match customer requirement as closer as possible.

Thanks.

Anderson

    Hello,

    The UCC28881 uses on off control and is hard switched it will not be able to achieve 15 mW of input power when the load is 30 mW.

    The standby power of less than 2 mW is not present with any TI solutions at this point in time.

    TI also at this time does not have devices for lower power applications that can operate at 150 C ambient tempature.

    Could you double check these requirements?
