Hi, TI expert.

SMPS block review applied to air conditioner model is in progress.

We ask for confirmation with a PWM IC with low standby power.

Please check the information below and request a suitable PWM IC recommendation.

-----------------------------------------------------------------------------------------------------------------------------------

- Output capacity: 15W (Based on actual load : 10W)

- Standby power: Between 10mW and 20mW or less.

  (No-load at 230VAC when supplied transformer bias, DC18V (primary), DC12V (secondary), DC5V (secondary) voltage must be alive.)

- Integrated FET or External FET (Does not matter)

-----------------------------------------------------------------------------------------------------------------------------------

The SMPS block diagram is as follows.

    Grady,

    Thanks for considering TI here!

    If you want secondary side regulation, I would consider UCC28740 here. If you prefer primary side regulation (no opto), take a look at UCC28730 which is lowest standby power in the industry for AC/DC Flyback.

    Regards,
    John
