MAX1708 Step-Up DC-DC Converter Evaluation Kit

The MAX1708 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 90% with output load currents to 2A. This EV kit operates at 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.
