Operation
Figure 1 shows a simplified diagram of the voltage regulation
and current control loops. Both voltage and current feedback
are used to precisely regulate voltage and tightly control the
output currents, I
L1
and I
L2
, of the two power channels. The
voltage loop comprises the error amplifier, comparators, gate
drivers and output MOSFETs. The error amplifier is
essentially connected as a voltage follower that has as an
input, the programmable reference DAC and an output that is
the CORE voltage.
Voltage Loop
Feedback from the CORE voltage is applied via resistor R
IN
to the inverting input of the error amplifier. This signal can
drive the error amplifier output either high or low, depending
upon the CORE voltage. Low CORE voltage makes the
amplifier output move towards a higher output voltage level.
Amplifier output voltage is applied to the positive inputs of
the comparators via the correction summing networks. Out-
of-phase sawtooth signals are applied to the two
Comparators inverting inputs. Increasing error amplifier
voltage results in increased comparator output duty cycle.
This increased duty cycle signal is passed through the PWM
CIRCUIT with no phase reversal and on to the HIP6601B,
again with no phase reversal for gate drive to the upper
MOSFETs, Q1 and Q3. Increased duty cycle or ON time for
the MOSFET transistors results in increased output voltage
to compensate for the low output voltage sensed.
Current Loop
The current control loop works in a similar fashion to the
voltage control loop, but with current control information
applied individually to each channel’s comparator. The
