Analog Simulation - LX7220
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.
