Introduction

NCV2575D2T-5R4G is a highly integrated, synchronous buck DC-DC switching voltage regulator which provides fast transient response and pre-emphasis of output voltage on dynamic load. This device integrates a low-side MOSFET and driver, buck controller, adaptive loop, and integrated high-side MOSFET in a compact package. This product is specifically designed to provide higher current in a compact form factor.

Application Field

The NCV2575D2T-5R4G are suitable for applications in liquid crystal displays (LCDs), digital televisions, server and notebook power designs, high - power factor LED lighting, medical equipment and industrial control systems. This integrated device provides the highest output current and efficiency in the smallest form factor.

Working Principle

The NCV2575D2T-5R4G operates with a fixed switching frequency of 500kHz, making it ideal for low-noise applications. The device features an adjustable output voltage, programmable switching frequency and pre-emphasis of the output voltage on dynamic load transients. A high-precision reference voltage of 1.2V and internal compensation are implemented to ensure fast transient response.The device features a wide variation of operating input voltage range, allowing up to 12V input. The output voltage can be set using an external divider, and allows for a wide range of output voltages from 0.6V to 5.25V. It is able to support an output current of up to 2.4A, and includes current sense, thermal shutdown and over voltage protection (OVP) to protect against fault conditions.
