MAX1709 Evaluation Kit  
General Description  
Features  
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  
0.7V to V  
Input Voltage Range  
OUT  
Pin-Selectable 3.3V or 5V Output Voltage  
(5V as Shipped)  
accepts a positive input between 0.7V and V  
and  
OUT  
converts it to a higher, pin-selectable output voltage.  
Adjustable 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.  
(2.5V to 5.5V, External Divider)  
Up to 4A Output Current  
600kHz PWM Operation  
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.
