Description

FULL DATA SHEET (PDF, 208kB) Download   E-Mail The MAX1858 evaluation kit (EV kit) demonstrates the MAX1858's standard application circuit. This dual PWM synchronous DC-to-DC converter generates outputs down to 0.75V for core, I/O, and logic supplies. The MAX1858 EV kit provides dual 1.8V and 2.5V output voltages from an 8V to 20V input voltage range. It delivers up to 10A output current for the 2.5V output and 10A for the 1.8V output with greater than 90% efficiency. Both converters operate 180 degrees out-of-phase to reduce input ripple current. The EV kit operates at 600kHz switching frequency and has superior line- and load- transient response. This EV kit is a fully assembled and tested circuit board. It allows evaluation of other output voltages in the 0.75V to 15V range. The MAX1858 EV kit can also be used to evaluate the MAX1875 and MAX1876.
