LX7165
Overview
The LX7165 is a digitally controlled step-down regulator IC with an integrated 30mohm high-side P-channel MOSFET and a 10mohm low-side N-channel MOSFET. It is an excellent choice for applications such as: Robotics, Industrial Control, Medical Instruments, Servers and Storage.
It features Microsemi’s proprietary constant-frequency hysteretic control engine for near-instantaneous correction to sudden line/load transients. It does not require high-ESR output capacitors and incorporates energy-saving “PSM” (Power Saving or Pulse Skip Mode) at light loads, to extend battery life in mobile applications.The LX7165 has an I2C serial interface port for output voltage margining and monitoring if required (it can operate in default mode too). It also includes robust fault monitoring functions. The LX7165 will operate from 3V to 5.5V, and is available in several fixed output voltage options from 0.6V to 0.97V (no voltage divider is necessary). The 0.6V version can be used for an adjustable output with an external voltage divider to achieve output voltages of up to 4.1V.
