The MAX17290 evaluation kit (EV kit) is a fully assembled and tested PCB that contains a 16W DC-DC boost converter for battery-operated, harsh environment, front-end preboost applications. The device integrates a low-side FET driver and current-mode, control-loop circuitry for output-voltage regulation, making it ideal for boost or SEPIC converters. The device’s integrated driver switches at 400kHz. The MAX17290 can be synchronized with an external clock source within the 100kHz to 1MHz range.
The EV kit operates from a DC supply voltage of 4.5V up to 7.3V. The EV kit can withstand a 16V line transient condition. The EV kit demonstrates the device features, such as dynamic adjustable output voltage, external clock synchronization, two-phase operation configurability, cycle-by-cycle current limit, hiccup mode, and thermal shutdown. The boost converter regulates 8V and can supply a current up to 2A. The EV kit also demonstrates a reference MAX17290 design for battery-operated, harsh environment applications.
