Product Details

The MAX8655 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that contains a fixed-frequency, pulse-width modulated (PWM) stepdown switching regulator. The MAX8655 EV kit provides a 1.2V output voltage from a 10.8V to 13.2V input source and delivers up to 20A output current. The MAX8655 IC features internal high-side and low-side power MOSFETs.

A reference input is provided for use with a high-accuracy external reference (REFIN) or for DDR and tracking applications. The MAX8655 EV kit operates at 600kHz. The MAX8655 IC has a programmable internal oscillator with frequency range from 200kHz to 1MHz. The MAX8655 can also be synchronized to an external clock by connecting the clock signal to FSYNC. A synchronization output (SYNCO) is provided to synchronize a second MAX8655 180° out-of-phase with the first by connecting SYNCO of the first MAX8655 to FSYNC of the second.
