SI-8090JD - Buck Converter

Download the SI-8090JD datasheet PDF. This datasheet also covers the SI-8050JD variant, as both devices belong to the same buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

SI-8000JD series are buck converter ICs whose maximum output current is 1.5 A.

These products have various functions including the Output On/Off Function, the Overcurrent Protection and the Thermal Shutdown, and achieve a buck converter circuit with few external components.

Key Features

  • High Efficiency 88% (SI-8120JD: VIN = 24 V, IOUT = 0.5 A).
  • Few Components.
  • Downsized Choke Coil (Switching Frequency 125 kHz (typ. )).
  • Fixed Output Voltage.
  • On/Off Function.
  • Low Supply Current during Output Off.
  • Protection Functions Overcurrent Protections (OCP): Fold-back Type, Auto-restart Thermal Shutdown (TSD): Auto-restart Typical.
