Introduction

The CS8140YTVA7 is a voltage regulator module (VRM) targeted for powering integrated circuits (ICs) in power electronic systems. It is a linear VRM, which offers cost-effective, efficient, and reliable power delivery to a wide range of application areas. The CS8140YTVA7 allows input and output voltages to be independently set and it can supply a large current to the load.

Application Field and Working Principle

The CS8140YTVA7 is suited for applications such as media processing, computer vision, or networking, which require an intermediate voltage to be regulated for the supply of high current loads. These applications typically require a linear voltage regulator because of the higher accuracy, low noise, and precision current limits that are associated with linear regulation. The CS8140YTVA7 is designed to provide a safe, efficient, and cost-effective way to power high current loads in such environments. A significant feature of the CS8140YTVA7 is its high-current capability, with maximum load current up to 20A. This is achieved by using a proprietary multi-phase synchronous rectification topology, coupled with a high-efficiency and low-dropout linear regulator.

The CS8140YTVA7 linear regulator module contains up to four internal high-side and low-side MOSFETs, as well as an input voltage sense circuit with feedback to the control circuitry, an operating frequency control PWM system, an output voltage selector, and an adjustable current limit circuit. The module provides accurate output voltage regulation by maintaining an internal reference voltage and sensing the voltage at the output of the MOSFETs. The current limit, over-voltage protection, and over-temperature shut-down functions are also built into the module for reliability and safety. The frequency of the PWM signal is adjustable by a resistor, allowing flexibility within the design. The module can also be configured to operate in a synchronous or non-synchronous mode.

The CS8140YTVA7 is specifically designed for use in high-current regulator applications, including power supplies for telecommunications and computer systems. The module offers wide input voltage capability, up to 36 V, and can accurately deliver output voltages from 0.6 to 6 V. Its high efficiency and high-speed transient response make it ideal for applications with switching speeds of up to 200kHz. Its advanced protection features and features such as over-voltage protection and over-temperature shut down ensure reliability and safety in system operation.

Conclusion

The CS8140YTVA7 is a linear voltage regulator module that is ideal for high current applications such as media processing, computer vision, or networking. It offers high-current capability and wide input and output voltage ranges with accurate regulation. Its advanced protection features and high speed transient response make it suitable for use in a wide range of applications. The CS8140YTVA7 provides an efficient and cost-effective way to power high current loads in power electronic systems.
