SI-8105QL - Step-Down Switching Regulator

General Description

The SI-8105QLis a step-down switching regulator IC, designed as an output voltage regulator at the secondary stage of switch mode power supplies.The current-mode control system permits small ceramic capac

Key Features

  • Current-mode control system employed.
  • Excellent line regulation (60 mV maximum).
  • 165 mΩ maximum on-resistance of built-in MOSFET.
  • Output current 3.5 A.
  • Wide range of input voltages (4.75 to 28 V), supports 24 V direct drive.
  • Output voltage 0.5 to 24 V, compatible with various IC power supply voltages, through low VREF of 0.5 V.
  • High efficiency, 94% maximum at VIN = 8 V, VO = 5 V, and IO = 0.5 A.
  • Operating frequency 350 kHz, supports downsizing of smoothi.
