描述

The MAX1709 evaluation kit (EV kit) is a step-up DC-DC switching regulator for 1- to 3-cell battery inputs as well as 2.5V or 3.3V regulated supply inputs. The EV kit accepts a positive input between 0.7V and VOUT and converts it to a higher, pin-selectable output voltage.

Efficiency is up to 87% with output load currents to 4A. This EV kit operates at a fixed 600kHz PWM frequency, allowing the use of a small inductor.

A movable jumper on the EV kit selects either a 3.3V or 5V output voltage. Additional pads on the board accommodate the resistors for output adjustment. This EV kit uses surface-mount components and is fully assembled and tested for quick evaluation.
