description of products:
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 I 2 C 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 3V to 5.5V, and is readily available in 4 fixed output voltage options: 0.8, 0.9V, 0.95V, and 0.97V (no voltage divider is necessary). After start up, the reference voltage can be adjusted with I2C with a resolution 4.7mV between 0.6V and 1.2V. The output voltage can also be adjusted with an external voltage divider up to 3.3V.
