Question

Difference between dc dc converter and dc dc controller

Answer 1

Virtually all battery-based power supplies must be custom-designed with supporting ICs that manage system operation. Some form of battery power management is employed in portable phones, MP-3 players, digital cameras, etc. This has been made possible by the availability of mixed-signal power management ICs that provide the required functions for increasingly complex electronic systems. Fig. 1 shows the basic power management subsystem employed in a battery-based system. Battery-based systems do not necessarily employ all these individual components, because multiple functions can now be integrated onto a single chip.

Generally, these power management subsystems must:
