The LM3432MH/NOPB is a high-efficiency, low-power, constant-current LED driver. It is an integrated component that combines a high-efficiency buck regulator, a 20V driver, and a 16-bit data interface designed to drive up to four strings of LED light sources. This component helps you to develop LED lighting applications quickly and easily, while delivering energy savings and programmability to achieve the desired brightness and color.

The LM3432MH/NOPB is a complete, programmable LED driver that is fully configurable through a simple, intuitive configuration tool. Integrated smart capabilities enable you to quickly customize parameters such as brightness/dimming, pulse-width modulation (PWM), output voltage, current, and light temperature. The tool also allows you to adjust the controller and output settings such as maximum current and output voltage, overcurrent limit, and PWM frequency.

This component features an innovative algorithm called PFM-Hybrid that constantly adjusts the output current to maintain a constant current. This algorithm optimizes the power efficiency of the system and reduces the power consumption of the overall system. It also reduces audible noise, harmonics, and radio frequency interference (RFI).

The LM3432MH/NOPB application field is driven LED lights with excellent current regulation and electromagnetic compatibility (EMC). It can be used in many LED lighting applications, such as street lighting, decorative lighting, security lighting, machine vision lighting, sign lighting, and LED backlighting for TVs and monitors.

This component is designed to be driven by the high efficiency PWM controller and the high current power switch. This enables maximum energy efficiency and stable performance. The integrated FET gate driver is optimized for high switching stability, while the integrated gate driver monitors the gate voltage level to ensure the FET gate is always maintained at the correct target voltage.

The LM3432MH/NOPB features a 16-bit interface, which provides precise control and dimming of LED brightness. This allows the driver to be easily integrated into a system and used as a part of a comprehensive LED driver solution. The integrated LED control interface is also supported by several popular lighting control protocols, such as 0–10V, DALI, DMX, wireless network, and Zigbee.

Overall, the LM3432MH/NOPB provides an efficient, reliable, and easy to use solution for driving up to four strings of LEDs. Its low power consumption, precise current regulation, and wide application range make it a highly desirable choice for a wide range of LED lighting applications.
