SGM66099B Product details

GENERAL DESCRIPTION
The SGM66099B is an ultra-low quiescent current synchronous Boost converter. 1.15V to 5.2V operation input voltage is suitable for Li-Mn battery, NiMH and Li-Ion rechargeable batteries. The 1.7μA (TYP) quiescent current maximizes the light load efficiency and also increases the effective battery operation time. In addition, the high-side synchronous rectifier provides output disconnect feature which minimizes unnecessary current drawn from the battery during shutdown mode.
The SGM66099B is able to deliver 300mA output current from 3.3V to 5V conversion, and achieves up to 93% efficiency at 200mA load.
The device provides down mode where the desired output voltage is regulated even when input voltage is higher than the output. In addition, when the input voltage is 300mV above the output voltage set point, the device enters pass-through mode.
The device integrates various protection features such as over-current protection, over-voltage protection and thermal shutdown. In addition, the synchronous rectifier supports short circuit protection which further improves the robustness of the device.
The SGM66099B provides both adjustable output voltage and fixed output voltage versions. It is available in Green WLCSP-1.22×0.83-6B and TDFN-2×2-6AL packages.
