Product SelectorRenesas 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 a power efficiency of 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 < 1mm, compared to inductor-based buck configuration.
This converter family allows system designers to transition from a 1S to a 2S system without any changes in their power tree. Switched capacitor DC/DC converters can also be used to directly charge single-cell Lithium batteries, reduce routing loss by 75%, and enable 3A USB cables to deliver up to 6A for charging.
