6 = DPWMC(n+1)

7 = DPWMC(n+2)

8 = DPWMC(n+3)

and for DPWMB:

0 = DPWMB(n) pass through (default)

1 = Edge-gen output, DPWMB(n)

2 = DPWNC(n)

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 DPWM4 the following definitions apply:

DPWM(n)

DPWM4

DPWM(n+1)

DPWM0

DPWM(n+2)

DPWM1

DPWM(n+3)

DPWM2

4.14 Filter

The UCD31XX 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
