WebThe charge pump is capable of delivering up to 500mA of output cur- rent and can be easily programmed in 16 steps with a single GPIO output through Skyworks' S2Cwire™ (Simple Serial Control) interface. This allows smooth transitions and flexible adjustment of brightness in flash or other lighting modes. WebCharge pumps are a form of DC-DC converter that rely on capacitors instead of inductors for energy storage and transfer. The absence of inductors makes them attractive in situations requiring a low-power auxiliary supply (output currents up to about 150mA). They use less circuit-board area, offer minimal component height, and are easy to use.
