    • Product Details

    The MAX8538 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8538 dual, PWM, synchronous buck controller. The EV kit uses an all-ceramic-capacitor solution to generate a 2.5V output voltage and a second 3.3V output voltage both at load currents up to 5A and an input voltage range of 4.5V to 23V. The switching frequency is set to 600kHz.
