The NCR405UX belongs to the family of PMIC – LED Drivers. It is an analog voltage mode constant current driver that powers an LED with a maximum power output of 4.05 watts. This device is designed to assist in reducing energy consumption and improve the system operation. It helps in improving the overall efficiency and performance of any electronic device. The NCR405UX is a high efficiency, low quiescent current, and fault tolerant driver IC. It offers protection against over-temperature, over-voltage, over-current and short-circuit prevention.

The NCR405UX is suitable for a wide range of portable consumer electronics, handheld systems, and solid state lighting applications. It is available in 4x4mm, 8-SIP package and 8-TSSOP package, with a maximum supply voltage of 10.5 V and a peak output current of 1.2 A. The device also features output regulation, peak current limit, and over-temperature protection.

The NCR405UX uses an advanced voltage-mode control architecture which enables it to precisely regulate an output current with an extremely high efficiency. The Switched Capacitor Pump (SCP) topology enables it to achieve good light efficiency and high load stability. The SCP architecture is more efficient and provides more accurate performance than conventional charge pump methods.

The NCR405UX can be used in variety of applications and is particularly effective for driving LEDs. It provides a wide range of features to enable the user to optimize the overall system performance. These features include programmable gain, adjustable current limit, short-circuit and over-current protection, and an adjustable output voltage. Furthermore, the IC also supports external synchronization and dimming control signals. It has an integrated current sensing circuit and on-chip thermal compensation which helps in regulating the output current over temperature variations.

The NCR405UX is an all-in-one solution for driving LEDs and provides an accurate and reliable current regulation. It features a wide input voltage range, adjustable current limit, over-voltage and over-temperature protection, and a very low quiescent current. The device is ideal for applications where the LED needs to be powered with low power consumption and high efficiency. It is a good choice for applications such as LED signage, Reading lights, Portable Sound Systems, Pagers, Wearable Devices, and Entertainment Systems.
