Figure 2. Block Diagram
The MAX17435/MAX17535 control input current (CCS
control loop), charge current (CCI control loop), or
charge voltage (CCV control loop), depending on the
operating condition. The three control loops, CCV, CCI,
and CCS, are brought together internally at the lowest
voltage clamp (LVC) amplifier. The output of the LVC
amplifier is the feedback control signal for the DC-DC
controller. The minimum voltage at the CCV, CCI, or
CCS appears at the output of the LVC amplifier and

clamps the other control loops to within 0.3V above the
control point. Clamping the other two control loops close
to the lowest control loop ensures fast transition with
minimal overshoot when switching between different
control loops (see the Compensation section). The
CCI loop is internally compensated and the CCV and
CCS loops share a common compensation network at
CC. The dominant control loop (CCV, CCS) drives the
compensation network.
