NCP4671DMX15TCG

The NCP4671DMX15TCG is a linear voltage regulator designed for applications containing a series of microprocessor cores and I/O devices in the power management chain. The device is a single 3A device intended to provide a full range of voltage conditions. It is an integrated single-chip solution with five low-power-loss linear regulators, up to three high-efficiency DC/DC synchronous buck converters, and two low quiescent current load switches installed in one package.

The NCP4671DMX15TCG device is intended to provide a full range of voltages needed by the system, while optimizing power efficiency and reducing component count. The integrated design allows the NCP4671DMX15TCG to be used in a variety of application spaces with minimal component count and easy integration. By using a single package for various voltage requirements, the NCP4671DMX15TCG helps to reduce system component count and cost.

In terms of functionality, the NCP4671DMX15TCG has five regulated low-dropout (LDO) linear voltage regulators, one voltage doubler regulator, two low quiescent current load switches, and three high efficiency DC/DC synchronous buck converters. All LDOs offer low current consumption and noise, while the two load switches provide a maximum on-resistance of 50mohm and a typical quiescent current of 16uA. All DC/DC buck converters are configured for step-down operation with up to 3A of output current, and offer synchronous internal compensation, high frequency operation (up to 500KHz), and adjustable current limit.

The NCP4671DMX15TCG offers some additional features, such as a programmable soft-start function, which reduces inrush current during start up to ensure system reliability. The device also offers overvoltage protection, short circuit protection and over temperature protection for increased safety and performance. Additionally, the device features a power-down mode for low power consumption, enabling the user to easily enter into a sleep state using the power-down command.

In terms of application field and working principle, the NCP4671DMX15TCG is capable of providing the complete power management chain including voltage regulation, over voltage protection, and power-down mode to a variety of applications. It works by using the LDO linear voltage regulators, supply voltage, and load switches in series with the DC/DC synchronous buck converters. During normal operation, the circuit will draw power from the supply voltage and step it down to the desired output voltage according to the requirements of the application. In the case of an over voltage condition, the device will detect the voltage spike and immediately shut down to avoid damage to the IC.

The NCP4671DMX15TCG is a highly sophisticated device that can provide voltage regulation, over voltage protection, and 5A of output current at various voltage requirements all in one functional package. The integrated design makes it easy to integrate into various systems, and offers a significant reduction in component count and cost. The NCP4671DMQ15TCG is an ideal solution for systems that require linear voltage regulation, power management, and protection from the effects of over voltage.
