General Description

The EM5841D is a high efficiency synchronous buck converter.

It can support 3.5A continuous output current. The constant

on-time control provides fast transient response and allows a

small footprint when designed all ceramic output capacitors.

Other features include internal soft-start, under-voltage

protection, over-voltage protection, cycle-by-cycle current

limit and thermal shutdown function. With aforementioned

functions, these parts provide customers a compact, high

efficiency, well-protected and cost-effective solutions. These

parts are available in DFN3.0X3.0-10 package.
