The WD3102 is a highly integrated Boost, LDO and inverting charge pump to generate positive and negative output voltage. The negative output voltages can be adjusted from -0.6V to -2.4V with 100 mV steps by SWIRE interface protocol. The part maintains the highest efficiency by utilizing a -0.33x/-0.5x mode fractional charge pump with automatic mode transition. With its input voltage range of 2.5V to 4.6V, WD3102 is optimized for products powered by single-cell battery and the output current up to 30 mA.

The WD3102C is available in CSP-15L package. Standard products is Pb-Free and Halogen-Free.
