Product Details

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 V_OUT, 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.

Applications

3.6V or 5V RF PAs in Communications Handsets
Local 2.5V to 3.3V or 5V Conversion
Local 3.3V to 5V Conversion
Routers, Servers, Workstations, Card Racks
