HI Sir

I have a 50mA LED driver (1ch) requirement (9~16Vin to 5Vout)

But need to use a voltage to control output current (analog dimming)

May I know TI have solution can be used for this application ?

I saw TPS92612 and TL4242 only have PWM dimming

Sorry, we don't have such parts with analog dimming.

We have TLC6C5712-Q1 12-ch part with 8-bit DAC to adjust the ouptut current through SPI interface. But it is a 12 channel part and the ouptut votlage is only 7V. I don't think it will help you on this application.
