Analog Devices MAX16990 | Demoboard MAX16990EVKIT

Description

The MAX16990/MAX16992 evaluation kits (EV kits)are fully assembled and tested PCBs that contain a16W DC-DC converter for front-end preboost automotiveapplications. The devices integrate a low-side FET driverand current-mode control-loop circuitry for output-voltageregulation, making them ideal for automotive boost orSEPIC converters. The MAX16990 integrated driverswitches at 400kHz, while the MAX16992 integrateddriver switches at 2.2MHz using the default configuration.The MAX16990 can be synchronized with an externalclock source within the 100kHz to 1MHz range, and theMAX16992 within the 1MHz to 2.5MHz range.The EV kits operate from a DC supply voltage of 4.5V(3V in bootstrapped mode) up to 36V. The EV kits canwithstand a 42V load-dump condition for up to 400ms.Each EV kit demonstrates the device features, suchas dynamic adjustable output voltage, external clocksynchronization, two-phase operation configurability,cycle-by-cycle current limit, hiccup mode, and thermalshutdown. The boost converter regulates 8V and cansupply a current up to 2A. Each EV kit includes an externalp-MOSFET (P1) that can be used to disconnect theboost output from the load in a fault condition. The EVkits also demonstrate a reference MAX16990 design forautomotive applications.
