MAX16813 Evaluation Kit Evaluates: MAX16813/MAX16813B General Description Benefits and Features The MAX16813 evaluation kit (EV kit) demonstrates 6.5V Up to HB LED Forward Voltage the MAX16813 high-brightness LED (HB LED) driver, Demonstrates OVP (33V) integrating a step-up DC-DC preregulator followed by 4 HB LED String Output Curren ts Configurable for channels of linear current sinks. The step-up preregulator 100mA or 150mA switches at 350kHz and operates as a current-mode- Demonstrates UVLO (4V) controlled regulator capable of providing up to 600mA for the linear circuits. Each of the 4 linear channels are Demonstrates Cycle-by-Cycle Current-Limit and capable of operating up to 40V and provide up to 150mA Thermal-Shutdown Features per channel. The 4 channels are configurable for 100mA Demonstrates Adaptive-Voltage Optimization or 150mA HB LED output current. Demonstrates Output Short Protection and The EV kit operates from a 6.5V DC supply voltage up Ultra-Low Current Shutdown to the HB LED string-forward voltage. The EV kit can Proven PCB and Thermal Design withstand a 40V load-dump condition for up to 400ms. The EV kit demonstrates the device features such as Fully Assembled and Tested adaptive voltage optimization, undervoltage lockout (UVLO), overvoltage protection (OVP), cycle-by-cycle Ordering Information appears at end of data sheet. 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 includes an external pMOSFET (Q2) that can be used to disconnect the boost output from the battery in the event of an output overload or short condition. The MAX16813 EV kit can also be used to evaluate the MAX16813B with simple IC replacement of U1.
