Power & Power Management

Renesas offers monolithic CMOS voltage conversion ICs that perform supply voltage conversions from positive to negative for an input range of 1.5V to 12V, resulting in complementary output voltages of -1.5V to -12V.

Switched Capacitor Converters

Renesas switched capacitor DC-DC converter technology is at the forefront of optimizing next generation mobile devices, with power efficiency over 98%. These converters can be used in cascaded configuration with PMICs to make 2S battery system power regulation more efficient and reduce PCB board area and component height to less than < 50% and height to < 1 mm, compared to inductor based buck configuration.

This converter family allows system designers to transition from 1S to 2S system without any changes in their power tree. Switched capacitor DC-DC converters can be also used for direct charging of single cell Lithium batteries, reduce routing loss by 75% and enabling the usage of 3A USB cables to deliver up to 6A for charging.
