Description
The EP53F8QI 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 40mm2.
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.
