SSP8099-ADJYT

The SSP8099 is a synchronous step-up converter. It is designed for products powered by alkaline battery, NiMH rechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation. The SSP8099 can support up to 300mA output current from 3.3V to 5V conversion, and achieve up to 90% efficiency at 200mA load. The SSP8099 also offers both down mode and pass-through operation for different applications. In down mode, the output voltage can still be regulated at target value even when input voltage is higher than output voltage. In pass-through mode, the output voltage follows input voltage. The SSP8099 exits down mode and enters into pass-through mode when VIN>VOUT+0.3V. The SSP8099 supports true shutdown function when it is disabled, which disconnects the load from the input supply to reduce the current consumption. The SSP8099 offers both adjustable output voltage version and fixed output voltage versions. It is available in Green WLCSP-1.22×0.83 -6B and TDFN-2×2 -6AL packages. The SSP8099 synchronous step-up converter is designed for alkaline battery, coin-cell battery, Li-Ion or Li-Polymer battery powered systems, which requires long battery running time and tiny solution size. The SSP8099 can operate with a wide input voltage from 0.9V to 5.2V. The SSP8099 operates in peak current mode with typical 1.3A peak switch current limit. The SSP8099 provides the true shutdown function and the load is completely disconnected from the input so as to minimize the leakage current. It also adopts down mode and pass-through operation when input voltage is close to or higher than the regulated output voltage. The SSP8099 is available in both adjustable and fixed output voltage versions.
