I am doing a lighting system which power source is solar panel, 17V and i need a DC/DC used a LED driver to drive 4xwhite LEDs in series (LED voltage is 3.2V). I intend to use TPS54232 and TPS62110(low iq) to drive the LED. I need dimming control, so can i use PWM signal at EN pin for dimming control?
Yes, as long as the dimming frequency requirement is slow enough to allow the IC to exit softstart and enter normal operation
