In addition, the device has excellent electromagnetic compatibility, allowing it to operate in noisy industrial or automotive environments.

Working Principle of S-812C42AMC-C2WT2U

The S-812C42AMC-C2WT2U is based on switch regulating element (SRE) technology, which is a switched-mode power supply (SMPS) type. This type of technology uses an inductor to store the energy during the high current draws, creating a voltage across the inductor. The energy stored in the inductor is then discharged during the low current draws. This operation is continuous and is how the S-812C42AMC-C2WT2U works.The device switches a transistor at high frequency (1.6MHz) to replenish the energy stored in the inductor. This ensures that the output voltage is regulated, eliminating most of the ripples and fluctuations in the output voltage. At the same time, the high switching frequency helps reduce the overall size of the component resulting in a very compact form factor ideal for portable applications. In addition, the S-812C42AMC-C2WT2U has built-in protection features like over-power, under-voltage, limiting current and over-temperature. These help to ensure that the device can survive a variety of operating conditions while delivering a regulated output voltage.

Conclusion

The S-812C42AMC-C2WT2U is a highly integrated step down switch mode DC/DC converter device from PMIC - Voltage Regulators - Linear.
