MAX16814EVKIT+

The MAX16814EVKIT+ from Maxim Integrated Products is a MAX16814 evaluation kit. It demonstrates the MAX16814 high-brightness LED (HB LED) driver, integrating a step-up DC to 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 HB LED string forward voltage. The EV kit can withstand a 40V load-dump condition. It also demonstrates the IC features such as adaptive voltage optimization, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, thermal shutdown and digital PWM dimming operation.
