NCP552SQ28T1 Application Field and Working Principle

NCP552SQ28T1 is a family of voltage regulators, which belong to the Linear category of PMIC – Voltage Regulators. It is specifically designed to reduce the fluctuation and ripple of output voltage for a variety of applications such as Voice over IP (VoIP) phones, DECT handsets, portable audio players, battery-powered equipment, and remote control systems.

The NCP552SQ28T1 is composed of an integrated circuit, which provides low noise, high precision voltage regulation and fast transient response, allowing the power supply to have optimal system performance. The regulator works in closed loop, in which the output voltage is compared to a reference voltage, and an output error signal is generated accordingly. This error signal is then amplified and applied to the output, controlling the load current and resulting in the output voltage being regulated accordingly.

The NCP552SQ28T1 is suitable for use in a variety of applications, including voice over IP phones, wireless digital communications systems, portable audio players, battery-powered equipment, and remote control systems. Its digital control and feedback loop enable the output voltage to remain stable regardless of changes in temperature, current load, or system voltage. In addition, its low quiescent current and low noise performance make it an ideal choice for cost-sensitive and portable applications or systems.
