    • Product Details

    The MAX5080 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX5080 PWM/PFM step-down converter IC with an integrated high-side switch. The MAX5080 EV kit operates over a wide 4.5V to 40V input voltage range and provides up to 1A at the 3.3V output.

    The MAX5080 internal switching frequency is set to 250kHz. The MAX5080 normally operates as a PWM converter and automatically switches to PFM mode at light loads to improve efficiency. The MAX5080 features a SYNC input to provide external frequency synchronization for noise-sensitive applications. The EV kit features PC board pads to evaluate the SYNC and ON/OFF-bar features of the MAX5080. The MAX5080 can operate over the automotive -40°C to +125°C temperature range. The MAX5080 step-down converter is suitable for FireWire®, automotive, and point-of-load applications.
