The LM36010EVM evaluation board is a versatile board for evaluating the various features of the LM36010 LED driver. It allows users to easily evaluate and optimize the performance of their LED-based applications. The board is capable of driving up to 2 LEDs in constant current mode, and up to 8 LEDs in PWM dimming mode. With its wide input voltage range from 4.2V to 34V as well as adjustable switching frequency from 200kHz to 1MHz, the board can accommodate a variety of LED configurations.

The LM36010EVM is an ideal solution for driving any type of LED application. It provides the user with flexibility and control over the output current, at the same time providing high efficiency. The board includes an on-board, high-accuracy current sense resistor, allowing the current output to be accurately set and monitored. Additionally, the board can be configured to support higher current outputs by adding external components to the board.

At the heart of the LM36010EVM is the LM36010, a high-performance, monolithic switching regulator. It integrates a power MOSFET, an error amplifier, an oscillator, PWM comparator, a current sense circuit, a temperature compensation circuit, and a power good indicator. This allows the device to easily control and regulate the output current of the LEDs, and provide excellent power efficiency.

The LM36010EVM application field also extends to battery-powered LED lighting, where LEDs are powered by a battery and require a minimal amount of energy to achieve maximum brightness and efficiency. Additionally, the board can be used for DC-DC converters and LED backlighting applications, as well as LED signs, indicator displays and emergency lighting systems.

The working principle behind the operation of the LM36010EVM is simple yet effective. The onboard error amplifier senses the output voltage and compares it to the set voltage and works to maintain a constant output voltage. When the output current is sensed to exceed the set value, the error amplifier switches the output voltage on and off, enabling the LEDs to be driven with accurate and efficient conditions.

The LM36010EVM is an invaluable tool for application engineers who need to test LED drivers. With its versatile and user-friendly design, the board allows developers to easily and accurately test the performance of LED drivers and optimize their LED-based designs.
