3 = DPWMA(n) (Crossover)
4 = DPWMA(n+1)
5 = DPWMB(n+1)
6 = DPWMC(n+1)
7 = DPWMC(n+2)
8 = DPWMC(n+3)
The DPWM number wraps around just like the Edge Gen unit. For DPWM3 the following definitions apply:
DPWM(n)
DPWM3
DPWM(n+1)

Filter
The UCD3138x filter is a PID filter with many enhancements for power supply control. Some of its features
include:
•
Traditional PID Architecture
•
Programmable non-linear limits for automated modification of filter coefficients based on received
EADC error
•
Multiple coefficient sets fully configurable by firmware
•
Full 24-bit precision throughout filter calculations
•
Programmable clamps on integrator branch and filter output
•
Ability to load values into internal filter registers while system is running
•
Ability to stall calculations on any of the individual filter branches
•
Ability to turn off calculations on any of the individual filter branches
•
Duty cycle, resonant period, or phase shift generation based on filter output.
•
Flux balancing
•
Voltage feed forward
