Product Details

The MAX17509 evaluation kit (EV kit) is a fully assembled and tested circuit board to demonstrate the performance of the MAX17509, a dual 3A, high-efficiency, synchronous step-down DC-DC converter. The EV kit operates from a 4.5V to 16V input voltage to generate two, independent 3.3V and 1.2V outputs, with each regulator delivering up to 3A continuous output current. The EV kit is preset to the default 1MHz switching frequency for optimum efficiency and component sizes, and each regulator operates 180° out-of-phase to reduce input-voltage ripple and total RMS input ripple current. The EV kit also features adjustable input undervoltage-lockout (UVLO), programmable frequency, external frequency synchronization input, adjustable output voltage ranging from 0.904V to 3.782V and 4.756V to 5.048V with 20mV resolution, selectable switching slew rate, adjustable soft- start time with soft-stop option, power-good outputs, and selectable overcurrent (OC) fault response to promote design flexibility and system reliability.
