3 = DPWMB(n) (Crossover)

4 = DPWMA(n+1)

5 = DPWMB(n+1)

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 DPWM3 the following definitions apply:

DPWM(n)

DPWM3

DPWM(n+1)

DPWM0

DPWM(n+2)

DPWM1

DPWM(n+3)

DPWM2

9.5.4 Filter

The UCD3138 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
