Description

The ACE758P provides high efficiency in a very small footprint. Featuring integrated inductor, the

device delivers up to 1500mA of continuous output current. Total solution footprint can be as little as

Output voltage is programmed via an external resistor divider providing a wide range of flexibility while

maintaining a very small footprint.

Integration of the inductor reduces conducted and radiated noise providing excellent compatibility with

sensitive RF and high speed data applications.
