Description
General part information
LX7220 Series
The LX7220 is a digitally controlled step-down regulator IC with an integrated 22mΩ high-side P-channel MOSFET and a 13mΩ 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 energysaving "PSM" (Power Save or Pulse Skip Mode) at light loads, to extend battery life in mobile applications. The LX7220 has an I 2C 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 LX7220 will operate from 2.7V to 5.5V, and is available in 0.95V or 0.9V output voltages (no voltage divider is necessary). The output voltage can also be adjusted with an input voltage of 5V and external voltage divider up to 3.3V.
