Each channel delivers up to 30 mA with a maximum output voltage of 39 V, making it suitable for driving multiple LED strings in series. ## Dimming flexibility and switching frequency Supports both analog and PWM dimming, giving the designer control over brightness via a DC voltage or a PWM input. The 1.25 MHz switching frequency allows the use of small external inductors and capacitors, shrinking the total solution footprint.
