MAX16813EVKIT# Datasheet PDF - Maxim Integrated

●The MAX16813EVKIT# from Maxim Integrated Products is an evaluation kit (EV kit) which demonstrates the MAX16813 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 linear circuits. Each of the 4 linear channels are capable of operating up to 40V and provide up to 150mA per channel. The 4 channels are configurable for 100mA or 150mA HB LED output current. The EV kit demonstrates the device features such as 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 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.
