PWM frequencies significantly higher than 1kHz
will be turned into analog dimming signals by the
input low pass filter of LED-Warrior01.
6. Regulator efficiency
The regulator efficieny depends on a number of
parameters. Since there are a couple constant
losses independent of the total power delivered by
the regulator the basic rule is that the regulator is
more efficient when used at higher power (i.e.
more LEDs connected). A lower difference
between input and output voltage does also
increase the efficiency.
