Single-input multiple-output DCDC converters with sequential outputs

A circuit portion comprising:

• a DCDC converter arranged to provide current from an output of the converter to a plurality of output loads;
• a power monitor arranged to monitor loading of one or more of the plurality of output loads;
• and
• channel logic circuitry configured to provide current cyclically from the output of the converter to each of the plurality of output loads according to a sequence that is repeated for a plurality of cycles, wherein:
• each cycle has a cycle duration;
• the cycle duration is divided equally into a plurality of discrete time slots;
• the channel logic circuitry is configured to provide current to each of the plurality of output loads during one or more of said discrete time slots;
• and
• the number of time slots is greater than the number of output loads, wherein the channel logic circuitry is configured to select the sequence, from a lookup table storing a plurality of predetermined sequence options, according to a value of a signal received from the power monitor;
• and
• wherein the lookup table stores at least:
• a first predetermined sequence option in which at least a first output load receives current for a different number of time slots in each cycle than a second output load;
• and
• a second predetermined sequence option in which at least a third output load receives current for a different number of time slots in each cycle than a fourth output loads.
