Production Datasheet
Description
The LX7165 is a digitally controlled step‐down regulator
IC with an integrated 40mΩ high‐side P‐channel
MOSFET and a 14mΩ low‐side N‐channel MOSFET. It
Features
Microsemi’s proprietary constant‐frequency hysteretic control engine for near‐instantaneous correction to line/load transients. It does not require high‐ESR output capacitors and incorporates energy‐ saving “PSM” (Power Save or Pulse Skip Mode) at light loads, to extend battery life in mobile applications.
The LX7165 has an I2C serial interface port for output voltage margining and monitoring if required (it can also operate in default mode). In addition it includes robust fault monitoring functions.
The LX7165 will operate from ...
