Working Principle

The S-1142A35H-E6T2U VRM is a low-noise, highly efficient voltage regulator module. It is designed to operate as an isolated, current-mode discrete linear voltage regulator with a wide operating voltage range of 4.5V to 28V and an output voltage range of 0.8V - 3.3V. The device includes an ultra low-dropout regulator (LDO), MOSFETs, and other necessary components to provide a high-reliability VRM solution. The module is capable of providing clean, stable power at frequencies ranging from 100kHz to 2.4MHz.

The S-1142A35H-E6T2U VRM is based on a voltage feedback control topology which consists of a fixed frequency, high-frequency switching regulator, coupled with an adjustable linear regulator. The switching regulator operates in current mode and is controlled by a voltage feedback loop. The linear regulator portion of the device adjusts the output voltage in response to changes in the input supply voltage, load, or environmental conditions. The regulation accuracy and output linearity are significantly enhanced by the combination of the switching regulator and the linear regulator.

The S-1142A35H-E6T2U is designed to have an output voltage that is adjustable over a wide range by means of a variable resistor which programs a set voltage. The output voltage can be programmed from 0.8V to 3.3V. The VRM operates over a wide range of input and output voltages and can handle high-current loads up to 30A.

Conclusion

The S-1142A35H-E6T2U is a low-noise, highly efficient voltage regulator module designed for use in applications that require a reliable, continuous supply of power. The module features an integrated linear regulator, high-frequency switching technology, and a wide input voltage range that make it suitable for a variety of applications. It is capable of providing clean, stable power at frequencies ranging from 100kHz to 2.4MHz and offers improved thermal performance and reverse polarity protection.
