FET used for dimming led driver could be replaced by BJT?

Hello,

We are doing a buckboost led driver using LM3429. (15W)

We want to flash the leds on and off at ~2Hz.

We intend to use the nDIM pin to do this.

... though can we use a BJT instead of a FET to take nDIM low and turn the leds off?

(example shown on page 14, figure 13 of datasheet)

Yes, any NPN BJT should work fine for that.
