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
output currents, IL1 and IL2, 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 RIN
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 HIP6601,
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
information used for this control is the voltage that is
developed across rDS(ON) of each lower MOSFET, Q2 and
Q4, when they are conducting. A single resistor converts
and scales the voltage across the MOSFETs to a current
that is applied to the Current Sensing circuit within the
HIP6301. Output from these sensing circuits is applied to the
current averaging circuit. Each PWM channel receives the
difference current signal from the summing circuit that
compares the average sensed current to the individual
channel current. When a power channel’s current is greater
