1.2MHz, 2A Output Current, Boost Converter YB1109M/YB1109MB  General Description The YB1109M/YB1109MB is a high efficiency current-mode boost converter with a fixed operation frequency. The YB1109M /YB1109MB hasbeen integrated a very low Rds-on NMOSFTET to reduce power loss and achieve high efficiency. The maximum efficiency is up to 93%. YB1109M/YB1109MB can output 2A current when VIN is higher than 3.3V and output is 5V. 1.2MHz operation frequency minimizes L and C value, and internal compensation network reduces external component counts. SOT23-6 package provides the best solution for PCB layout area.  Features · WideInputRange: 2.5-6V Input,· · YB1109M/YB1109MB Up To 2A Output Current · 1.2MHz Switching Frequency · Low RDS(ON): 70mΩ · Up to 93% Efficiency .
