SI-8033SD - 3A Buck Converter

Download the SI-8033SD datasheet PDF. This datasheet also covers the SI-8000SD variant, as both devices belong to the same 3a buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

SI-8000SD series are buck converter ICs whose maximum output current is 3 A.

These products have various functions including the Soft Start Function, 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 84% (SI-8050SD: VIN = 20 V, IOUT = 1 A).
  • Few Components.
  • Downsized Choke Coil (Switching Frequency 60 kHz (typ. )).
  • Fixed Output Voltage.
  • Soft Start Function.
  • On/Off Function.
  • Low Supply Current during Output Off.
  • Protection Functions Overcurrent Protections (OCP): Drooping Type, Auto-restart Thermal Shutdown (TSD): Auto-restart Typical.
