Product Details

The MAX8792 evaluation kit (EV kit) demonstrates the standard 10A application circuit of the MAX8792. This DC-DC converter steps down high-voltage batteries to generate low-voltage core or chipset/RAM bias supplies in notebook computers.

The MAX8792 EV kit provides a dynamically adjustable 1.5V/1.05V output voltage from a 7V to 24V battery-input range. It delivers up to 10A output current while achieving greater than 90% efficiency. Programmed by a single resistor, the EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.

The EV kit is a fully assembled and tested PCB. It also allows the evaluation of other dynamically adjustable output voltages by varying the external reference input, which can be realized by changing resistors R1, R2, and R3.
