SI-8120TM - DC/DC Step-Down Converter

This page provides the datasheet information for the SI-8120TM, a member of the SI-8000TM DC/DC Step-Down Converter family.

Datasheet Summary

Description

SI-8000TM series has 300kHz oscillation frequency, so it contributes miniaturization of a chalk coil.

Therefore, it realizes a compact and high efficient power supply together with TO 252-5 package (compatible:SC-63) .

Features

  • br>.
  • 1.5A output current by compact power surface mount package.
  • High Efficiency 81% (at VIN=15V, Io=0.5A,Vo=5V).
  • Requires only four discrete components. (C3: required for soft start. ).
  • Built-in Oscillation circuit (oscillation frequency : 300kHz (TYP)).
  • Constant current type overcurrent protection and overheating protection.
  • Soft start function. (ON/OFF function available. Output OFF at Low level. ).
  • Low consumption current at Output OFF. Input Voltage Output Current.
