SiC437 - DC/DC Converter

General Description

The SiC43x are synchronous buck regulators with integrated high side and low side power MOSFETs.

Its power stage is capable of supplying 12 A (SiC437) and 8 A (SiC438) continuous current at up to 1 MHz switching frequency.

Key Features

  • Versatile - Operation from 3 V to 28 V input voltage - Adjustable output voltage down to 0.6 V - Scalable solution 8 A (SiC438), 12 A (SiC437), and 24 A (SiC431) - Output voltage tracking and sequencing with pre-bias start up - ± 1 % output voltage accuracy at -40 °C to +125 °C.
  • Highly efficient - 97 % peak efficiency - 1 μA supply current at shutdown - 50 μA operating current not switching.
  • Highly configurable - Four programmable switching frequencies available: 300.

Its power stage is capable of supplying 12 A (SiC437) and 8 A (SiC438) continuous current at up to 1 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 3 V to 28 V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial. SiC437’s and SiC438’s architecture delivers ultrafast transient response with minimum output capacitance and tight ripple regulation at very light load.
