The NCR402UH is a LED Driver that is an intelligent choice for both solid-state lighting (SSL) and general purpose LED applications. It features a dual-channel design with a single-channel input, high efficiency, low output ripple voltage and excellent thermal performance.

The NCR402UH integrates control and protection circuits, so it can offer superior protection against short circuiting, overvoltage, and overcurrent. Its high efficiency power conversion enables a minimum of 94% electrical efficiency and up to 90% output power. Specifically designed for application in theSolid-State Lightening (SSL) and general purpose LED area, the NCR402UH is suitable for use in fields such as media displays, Medical lighting, automotive/industrial, architectural lighting and signage.

In terms of its working principle, the NCR402UH has two independent channel output current. Each channel can be adjusted via the input voltage. The voltage to current inside is regulated through the PMOS/PDMOutput stage depending on the requirements of the application. The open loop operation provides the current feedback which is used to adjust the output current through the linear compensation.

In terms of application-field,the NCR402UH is primarily used in SolidState Lightening (SSL) and general purpose Led applications. This LED Driver can be used in various installations such as media displays, automotive/industrial, medical lighting, architectural lighting and signage. The NCR402UH’s dual-channel design allows it to drive two independently-controlled LED strings and LED arrays, with a maximum current of 1.2 A per channel.

It is also widely used in the telecommunications industry. Besides providing high efficiency power conversions, it also gives excellent thermal performance. The NCR402UH is suitable for applications at temperatures up to125°C, making it ideal for small cell base stations and telecom cabinets.

With its high efficiency, low output ripple voltage, excellent thermal performance, and wide range of applications, the NCR402UH is an intelligent choice for LED Drivers. It has a dual-channel design, dual-channel output, variable input voltage, and low voltage operation, making it a cost-effective and reliable solution for a variety of applications.
