Description

The MAX16814 evaluation kit (EV kit) demonstrates the MAX16814 high-brightness LED (HB LED) driver, integrating a step-up DC-DC preregulator followed by 4 channels of linear current sinks. The step-up preregulator switches at 350kHz and operates as a current-mode-controlled regulator capable of providing up to 600mA for the linear circuits. Each of the 4 linear channels can operate up to 40V and provide up to 150mA per channel. The 4 channels are configurable for 100mA or 150mA HB LED output current. The IC is a 20-pin TSSOP package with an exposed pad for enhanced thermal power dissipation.

The EV kit operates from a DC supply voltage of 6.5V up to the HB LED string forward voltage. The EV kit can withstand a 40V load-dump condition. The EV kit also demonstrates the IC features such as adaptive voltage optimization, undervoltage lockout (UVLO), overvoltage protection (OVP), cycle-by-cycle current limit, thermal shutdown, and digital PWM dimming operation using a digital PWM input signal to control the brightness of the HB LEDs. The EV kit also demonstrates a reference IC design for automotive applications.
