General Description
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.
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). The output voltage can also be adjusted
with an input voltage of 5V and external voltage divider
up to 3.3V.
