TPS54200: How to use analog dimming ?

future chang1

Part Number: TPS54200
Other Parts Discussed in Thread: TPS92200

Hello Sirs,

Is it possible to dimming control TPS54200 from a DAC directly?

So analog 3V can set reference voltage to 200mV.

Analog 1.5V can set reference voltage to 100mV.

Analog 0.6V can set reference voltage to 40mV.

The above setting is correct ?

Is there any item I need to pay a attention to ?

best regards

Hi,

Yes, this device supports analog dimming. TPS92200 is the latest device similar with TPS54200. Pls refer the datasheet of TPS92200.

Hi Robin:

I know TPS92200 is similar with TPS54200.

But there is no TPS92200 in the stock.

I can only wait for the stock notification.

Or when will there be TPS92200 in the stock?

One week, 4 weeks, or 8 weeks ?

best regards
