MAX1709 Evaluation Kit
General Description
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 V_OUT 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.
