The EA6360US is an evaluation board designed for LED modulation drivers. It has a wide range of commercial and industrial applications, making it a versatile choice for various lighting projects. The evaluation board is designed for use with the Texas Instruments LM3430, a highly versatile current mode controller for narrow bandwidth PWM dimming of LEDs. The EA6360US also supports high speed integral dimming of up to 6kHz, allowing it to be used to dim high frequency monochromatic LEDs in a very efficient manner.

The EA6360US is designed to make use of the LM3430’s flexible frequency response and internal topology, to minimize component count. The evaluation board is also designed to maximize system efficiency and reduce overall system cost by utilizing the LM3430’s high efficient active voltage regulation loop, which reduces RMS inductor current ripple during light emission. It also includes a true current sink, allowing the feedback loop to be configured in either buck-boost or “boost-boost” inversion configurations.

The EA6360US application field and working principle revolves around the LM3430 controller, which can be used with a variety of different LEDs in different configurations and driving scenarios. The LM3430 is designed for high efficiency power supply design, with a 400mV minimum voltage drop at 1A or below, and a wide switching frequency range of 0.4MHz to 6MHz. It supports a variety of LED dimming methods, including pulse width modulation (PWM) and pulse density modulation (PDM). The LM3430 is also capable of high dynamic frequency PWM dimming of small monochromatic LEDs with small duty cycle ratios.

The LM3430 is also designed for high speed current mode operation and is capable of dynamic frequency scaling, allowing the LED driver to operate at variable frequencies between low and high current levels. This can help reduce harmonic content as well as further improve efficiency and reduce heat dissipation issues. Additionally, the LM3430 also supports low stand-by current design, only consuming a few microamps when in standby.

In addition to the main LED drive capabilities, the EA6360US evaluation board also supports a variety of system related features including over-voltage protection, over-current protection, fault diagnosis, and a logic interface. Additionally, the LM3430 features a programmable thermal threshold, which allows the user to set a temperature at which the system will shut off to prevent heat damage to the components.

Overall, the EA6360US evaluation board is a versatile and feature packed choice for LED applications. Featuring a range of features designed to help improve system efficiency and reduce overall system cost, the LM3430 offers great performance for a variety of commercial and industrial applications.
