 Supported Range of Frequency and Duty Resolution

-The LED PWM Controller is designed primarily to drive LEDs and provides wide resolution of PWM duty settings. For instance for the PWM frequency at 5 kHz, the maximum duty resolution is 13 bits. It means that the duty may be set anywhere from 0 to 100% with resolution of ~0.012% (13 ** 2 = 8192 discrete levels of the LED intensity).

 The LEDC may be used for providing signals at much higher frequencies to clock other devices, e.g. a digital camera module. In such a case the maximum available frequency is 40 MHz with duty resolution of 1 bit. This means that duty is fixed at 50% and cannot be adjusted.
