The EA8105 is a high switching frequency, high efficiency synchronous buck regulator, designed to operate from 2.5V to 5.5V input voltage range.

Built-in low R_DS(ON) high/low side Power-MOSFETS not only reduce external components and has up to 96% efficiency, ideal for 1.5A output current applications.

The EA8105 features 100% duty cycle low dropout operation, extending battery life in portable systems.

Besides, this device is designed to take into account the light load mode operation and can provide high efficiency over a wide range of the load current.

The internal compensation design not only allows users to more simplified application, and can reduce the cost of external components.

The EA8105 is available in the SOT-23-5 package and easy to use.
