Analog Simulation - LX7219
The LX7219 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 energy-saving “PSM” (Power Save or Pulse Skip Mode) at light loads, to extend battery life in mobile applications.
The LX7219 will operate from 2.7V to 5.5V and is available in 0.9V single slave address and 0.8V default output voltage (no voltage divider is necessary) with 4 slave addresses. The output voltage can also be adjusted with an external voltage divider up to 3.3V.
