NCP1400ASN19T1

The NCP1400ASN19T1 is a high-efficiency, DC/DC step-down switch mode converter that operates with a wide input voltage range and is suited for the most demanding applications. The device isconfigured in a current-mode, non-synchronous buck topology and utilizes an internal N-channel MOSFET switch to deliver up to 1.1A output current at a regulated output voltage as low as 1.2V under full load conditions. With its excellent current and voltage rippleness and low EMI characteristics, the NCP1400ASN19T1 is an ideal solution for applications ranging from mobile devices to embedded systems to even industrial automation and control.

This highly scalable device is designed to function as both a primary input supply or as a low voltage output regulator, depending on the application. With its wide input range, the device can handle input voltages up to 28V, making it flexible for a variety of applications including sensor inputs, industrial automation, and battery-powered devices, among others. The device also features excellent thermal performance and can withstand short circuit operation, enabling robust operation in harsh environments.

The NCP1400ASN19T1 works in a constant frequency current-mode architecture, providing excellent regulation accuracy and matching the output voltage ripple to the switching frequency of the device. The power supply operates at a fixed frequency with a low noise, narrow pulse width modulated (PWM) switching-mode operation that reduces the amount of EMI generated. The device also features on-board protection against over-voltage, under-voltage, brown-in, over-temperature and short circuit conditions, helping to ensure long-term operation in a wide range of applications.

The NCP1400ASN19T1 is an ideal solution for applications that require a low input voltage, a small footprint and an affordable price point. This device is further enhanced with a proprietary user-programmable parameter set that allows power designers to fine-tune the switching frequency and other parameters to meet specific application requirements. With its sleek and easy-to-use design, the NCP1400ASN19T1 is an excellent choice for applications in mobile, industrial, and embedded systems.
