The LM36923HEVM evaluation board is a high-end LED driver intended for automative and other applications. It is designed for high-efficiency, low profile and low-temperature operation. The LM36923HEVM can drive up to 6 LEDs and is provided with analog dimming control from 0.1V to 13.5V. The driver is also capable of light flash adjustment, digital dimming with pulse width modulation (PWM), and voltage control.

The device features a pre-driver circuit stage with two N Channel MOSFETs, an internal synchronous rectification circuit, and an active current-limiting circuit. The synchronous rectification eliminates the need for external snubbers and reduces power dissipation. The pre-driver stage helps to ensure uniform current through the LEDs, even during dimming or changes in load conditions. The integrated active current limit helps to ensure that the appropriate LED current is maintained during all operating conditions.

The LM36923HEVM is a ready-to-use evaluation board with multiple inputs to let the user control LED brightness, LED output current, LED temperature, LED pulse control, and LED pulse width modulation (PWM) dimming. It is compatible with TMS320F2800/2805 DSPs, dsPIC DSCs and PIC32MZ microcontrollers, as well as Arduino and other development boards.

The main features of the LM36923HEVM evaluation board are its high efficiency, low profile design, and flexible dimming and pulse width modulation (PWM) capability. The activity of the device is controlled through a web browser, with simple drag and drop interface. This makes it easy for the user to configure their application with minimal effort. The device is also capable of providing diagnostic information for debugging purposes. Finally, the LM36923HEVM also provides over-temperature protection, lockout voltage protection, power shutdown and start-up phase for safe and reliable operation.

The LM36923HEVM is well suited for automotive lighting applications, as well as other applications where low-profile, high-efficiency LED drivers are needed. The evaluation board enables users to quickly and easily evaluate the performance of the LED driver in different applications, and to optimize the LED brightness, current, temperature and PWM settings. The LM36923HEVM provides a smart solution for customers looking for an LED driver with advanced features and performance.
