Evaluates: MAX16814 19-4947 Rev 1 5/10 MAX16814 Evaluation Kit General Description Features The MAX16814 evaluation kit (EV kit) demonstrates S Input Voltage from 6.5V Up to HB LED Forward the MAX16814 high-brightness LED (HB LED) driver, Voltage integrating a step-up DC-DC preregulator followed by 4 S Demonstrates OVP (33V) channels of linear current sinks. The step-up preregula- S HB LED String Output Currents Configurable for tor switches at 350kHz and operates as a current-mode- 100mA or 150mA controlled regulator capable of providing up to 600mA S Demonstrates UVLO (5V) for the linear circuits. Each of the 4 linear channels can operate up to 40V and provide up to 150mA per channel. S Demonstrates Open and Short LED Fault The 4 channels are configurable for 100mA or 150mA Protection and Detection HB LED output current. The IC is a 20-pin TSSOP pack- S Demonstrates Cycle-by-Cycle Current Limit and age with an exposed pad for enhanced thermal power Thermal-Shutdown Features dissipation. S Demonstrates Adaptive Voltage Optimization The EV kit operates from a DC supply voltage of 6.5V S Proven PCB and Thermal Design up to the HB LED string forward voltage. The EV kit can withstand a 40V load-dump condition. The EV kit also S Fully Assembled and Tested demonstrates the IC features such as adaptive voltage optimization, undervoltage lockout (UVLO), overvoltage protection (OVP), cycle-by-cycle current limit, thermal Ordering Information shutdown, and digital PWM dimming operation using a PART TYPE digital PWM input signal to control the brightness of the MAX16814EVKIT+ EV Kit HB LEDs. The EV kit also demonstrates a reference IC design for automotive applications. +Denotes lead(Pb)-free and RoHS compliant.
