Microchip Technology LX7220
LX7220 is a digitally-controlled step-down regulator IC with an integrated 22 mΩ high-side P-channel MOSFET and a 13 mΩ low-side N-channel MOSFET. It features Microchip 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.| Part No. | LX7220 |

GENERAL DESCRIPTION
LX7220 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. 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).
