Because PCB size matters
Dialog Semiconductor debuted the inductor-less, 50W DA9313 switched capacitor DC-DC converters. The high-efficiency device can power more than 50W in less than 10 mm2 of board area, allowing developers to extend battery life and reduce charging time in direct charging and 2S lithium-ion (Li-ion) systems such as notebook PCs, DSLR cameras and portable Bluetooth speakers.
“We basically used cascoded regulating which significantly lessened the height and size of the PCB and eliminates expensive inductors, ” says Patrick Fournier, Dialog Semiconductor’s Principal Applications Engineer.
