LX7165 - 5A Constant Frequency Hysteretic Synchronous Buck Regulator

General Description

MOSFET and a 14mΩ low‐side N‐channel MOSFET.

Key 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 .
