Input voltage0.7-5.5 V
Output 15 V
IC revision00

Description

The SGM66099A is an ultra-low quiescent current synchronous Boost converter. 0.7V to 5.5V operation input voltage is suitable for Li-Mn battery, NiMH and Li-Ion rechargeable batteries. The 0.6μA (TYP) quiescent current maximizes the light load efficiency and also increases the effective battery operation time. The SGM66099A is able to deliver 300mA output current from 3.3V to 5V conversion and achieves up to 93% efficiency at 200mA load. The SGM66099A offers down mode and pass-through mode. In down mode, the desired output voltage is regulated even when the input voltage is higher than the output. In addition, when the input voltage is 270mV above the output voltage set point, the device enters pass-through mode. In pass-through mode, the output voltage follows input voltage.
