Silicon Mitus Designs Very High Efficiency Switched Capacitor for Fast Charging Applications

The SM5428 offers the highest figures in efficiency and output
current while guaranteeing safety

SEOUL-PANKYO, South Korea–(BUSINESS WIRE)–#BatteryCharger—Silicon
Mitus, an advanced specialist in PMIC technology, announced the
SM5428, a Switched Capacitor Battery Charger. The DC-DC converter has
been highly optimized to meet the demands of the emerging fast charging
applications in the USB Type-C market, offering a higher efficiency that
allows for a reduced time to charge the battery and better management of
the thermal dissipation during the recharging cycle of the device. It is
tailored specifically for smartphones, tablets and any other battery
powered consumer devices.

The SM5428 integrates the companyÔÇÖs most efficient converter with the
highest output charger current to date. It reaches a peak efficiency of
98 percent and a maximum output current of 8 A to support 35 W of
charging power. It also integrates 10-bit ADC to measure the VBUS input
voltage, VBAT output voltage, current and die temperature. Furthermore,
the serial I2C interface and numerous battery protection
schemes help minimize heat dissipation while doubling the power, thereby
reducing costs for designers. This allows for an efficient, safe and
cost-effective solution for fast charging in consumer applications that
are taking full advantage of the latest USB Type-C PD3.0 standard.

ÔÇ£The introduction of SM5428 underscores Silicon MitusÔÇÖs long term
commitment to delivering innovation in the computing and consumer
applications within the USB Type-C ecosystem,ÔÇØ said Gianfranco Scherini,
VP of Business Development of Silicon Mitus based in Cupertino,
California. ÔÇ£The device is a recent addition to our current line of USB
Type-C compatible products, which also include Type-C CC controllers,
OVP protections and eMarker ICs.ÔÇØ
