The EA8253 is a 3A buck regulator, designed to operate from 4.6V to 23V input voltage range.

Built-in low R_DS(ON) high/low side Power-MOSFETS not only reduce external components and has up to 94% efficiency, ideal for 3A output current applications.

The EA8253 is designed to take into account the light load mode operation. At output loading 10mA condition, the efficiency up to 80%.

The EA8253 has complete protection functions, including cycle-by-cycle current limit, short circuit protection, OVP, OTP and UVLO protection.

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

The EA8253 is available in the SOP-8 (with EP) package and has a good cooling effect and easy to use.
