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.
