General Description

The SI-8005Q is 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 capacitors to be used as output capacitors.

Together with the compact HSOP8 package, this allows reduction of regulator circuitry area on the PCB by approximately 50% in comparison with conventional topologies.

Designed to save power, losses in the SI-8005Q are reduced by controlling the maximum on-resistance of a built-in output MOSFETto as low as 165 mΩ.

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 500 kHz, supports downsizing of smoothi.
