Single-chip buck-boost DC-DC converter for USB-C chargers
The SM58IP04 DC-DC converter includes integrated FETs for designs up to 65W and reduces the PCB footprint by half with a height of under 1.2 mm.
The DC-DC converter has an efficiency of up to 95% efficiency in both buck- or boost-mode charging the battery up to 6 A from advanced thermal management in the chip. It also supports both Direct and Parallel Charging, Intel IMVP8 and Cell Balancing while integrating multiple currents and voltages sensing and overvoltage protection features.
“We are extremely satisfied with the traction of SM58IP04 in computing and power bank applications where the product has been proven to be very effective in delivering great performance and cost saving,” said Gianfranco Scherini, VP of Business Development of Silicon Mitus based in Cupertino, California. “Leveraging our experience in integrating complex analog and digital functions in a single IC, typical of the mobile industry, we deliver the first product that combines the features of a multi-cell battery charger with the full support of the USB Type-C and PD specification.”
The device is available in a 77 Pin WLCSP package, and samples are available.
