Figure 2. Block Diagram

The MAX17035/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.
