EVALUATION KIT AVAILABLE  
4A, Low-Noise, High-Frequency,  
Step-Up DC-DC Converter  
MAX1709  
General Description  
Benefits and Features  
The MAX1709 sets a new standard of space savings  
for high-power, step-up DC-DC conversion. It delivers  
up to 20W at a fixed (3.3V or 5V) or adjustable (2.5V to  
5.5V) output, using an on-chip power MOSFET from a  
+0.7V to +5V supply.  
• Integration Reduces External Component Count to  
Save Space  
• On-Chip 10A Power MOSFET  
• 5V, 4A Output from a 3.3V Input  
• Fixed 3.3V or 5V Output Voltage or  
Adjustable (2.5V to 5.5V)  
Fixed-frequency PWM operation ensures that the  
switching noise spectrum is constrained to the 600kHz  
fundamental and its harmonics, allowing easy postfilter-  
ing for noise reduction. External clock synchronization  
capability allows for even tighter noise spectrum con-  
trol. Quiescent power consumption is less than 1mW to  
extend operating time in battery-powered systems.  
• Input Voltage Range Down to 0.7V  
• Constant Frequency Reduces Post-Filtering  
• Low-Noise, Constant-Frequency Operation  
(600kHz)  
• Synchronizable Switching Frequency  
(350kHz to 1000kHz)  
Two control inputs (ONA, ONB) allow simple push-on,  
push-off control through a single momentary pushbut-  
ton switch, as well as conventional on/off logic control.  
The MAX1709 also features programmable soft-start  
and current limit for design flexibility and optimum per-  
formance with batteries.  
• Lower Power Consumption Extends Battery Life  
• 1mW Quiescent Power  
Ordering Information  
The MAX1709 is supplied in both a high-power TSSOP  
package, which allows a 10A  
switch current and a  
RMS

4A output, and a narrow SO package, which supplies a  
2.4A output with a switch rated at 6A . Although the  
MAX1709ESE  
MAX1709EUI+  
RMS  
narrow SO device has a lower RMS switch rating, it has  
the same peak switch current rating as the TSSOP  
device, and so can supply 4A loads intermittently. If  
loads of 2A or less are required, refer to the MAX1708.
