Product Details

The MAX1993 evaluation kit (EV kit) demonstrates the MAX1993's standard 4A application circuit. This DC-to-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage rail for use as chipset, DRAM, and other low-voltage supplies.

The MAX1993 EV kit provides a dynamically adjustable 1.0V/1.5V output voltage from 7V to 24V battery input range. It delivers up to 4A output current with greater than 90% efficiency. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.

This EV kit is a fully assembled and tested circuit board. It also allows the evaluation of other dynamically adjustable output voltages in the 0.7V to 5.5V range by changing R6, R7, and R8 resistors.

This EV kit can also be used to evaluate the MAX1992, which has preset 1.8V/2.5V output voltages.
