1. DESCRIPTION
The EP53F8QI is an Intel® Enpirion® Power System on a Chip (PowerSoC) DC-DC converter. The EP53F8QI provides high efficiency in a very small footprint. Featuring integrated inductor, MOSFET switches, small-signal circuits and compensation in an advanced 3mm x 3mm x 1.1mm 16-pin QFN package. 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.
