POWER


Achieve more power for low voltage applications with 2-phase


monolithic boost converter By Michael Wu, staff applications engineer, Analog Devices


M


onolithic boost converters can convert low input voltages to a higher output voltage all in a compact solution size. However, when the output power requirements increase, so do current levels and heat dissipation. Limitations from the internal switch make it  boost converter can be better suited for these types of applications.


By interleaving the switching action of the converter into two phases, the switch current ripple is effectively cut in  well as improved thermal performance.
