Description

The MAX1864 evaluation kit (EV kit) demonstrates the MAX1864’s standard application circuit. This EV kit operates from 8V to 24V, generating three positive output voltages.

The MAX1864 EV kit includes a current-mode synchronous step-down controller and two positive regulator gain blocks. The main synchronous step-down controller provides a 3.3V output voltage with 1A output current from an 8V to 24V input voltage range. The positive regulator gain blocks use an external PNP pass transistor to generate 2.5V with 300mA output current from the main 3.3V output, and 5V with 100mA output current using coupled windings from the step-down converter. The EV kit operates at 200kHz switching frequency, allowing the use of low-cost aluminum electrolytic capacitors and a low-cost power transformer.

This EV kit is a fully assembled and tested circuit board. It also allows the evaluation of other main output voltages in the 1.236V to 5.5V range by installing feedback resistors R8 and R9.
