Using ISL8036 integrated power controller circuit can be designed a very simple high efficiency power supply . The maximum output current that can be provided by this power supply circuit is around 3A . output current or current sharing .
The input voltage range is from 2.8V to 6V, allowing for the use of a single Li+ cell, three NiMH cells or a regulated 5V input. The two channels are 180 degrees out of phase, and each one has a guaranteed minimum output current of 3A but they can be combined to form a single 6A output in the current sharing mode.
A very simple high efficiency switching mode buckboost power supply circuit can be designed using the LTM4609 switching regulator IC . This switching power supply circuit will provide an fixed output voltage of 32 volt . As you can see in the schematic circuit , this switching power supply circuit require few external electronic components .
Included in the package are the switching controller, power FETs and support components.
A very simple high efficiency , high power switching 24v power supply schematic circuit that can provide a maximum output current of 10A at 24 volt output voltage can be designed using the LTC3787 high performance PolyPhase single output synchronous boost converter controller that drives two N-channel power MOSFET stages out-of-phase.
