Step-Down DC-DC Regulator with Internal Switches  
MAX5041  
General Description  
Features  
♦ Up to 3A of Continuous Output Current  
The MAX15041 low-cost, synchronous DC-DC convert-  
er with internal switches delivers an output current up to  
3A. The MAX15041 operates from an input voltage of  
4.5V to 28V and provides an adjustable output voltage

The MAX15041 is ideal for distributed power systems,  
preregulation, set-top boxes, television, and other con-  
sumer applications.

♦ Sꢁfe Stꢁrtup into Prebiꢁsed Output  
♦ Enꢁble Input ꢁnd Power-Good Output  
The MAX15041 features a peak-current-mode PWM con-  
troller with internally fixed 350kHz switching frequency  
and a 90% maximum duty cycle. The current-mode con-  
trol architecture simplifies compensation design, and  
ensures a cycle-by-cycle current limit and fast response  
to line and load transients. A high-gain transconductance  
error amplifier allows flexibility in setting the external com-  
pensation by using a type III compensation scheme,  
thereby allowing the use of all ceramic capacitors.  
♦ Fullc Proteꢀted Agꢁinst Oꢂerꢀurrent ꢁnd  
Oꢂerteꢄperꢁture  
This synchronous buck regulator features internal  
MOSFETs that provide better efficiency than asynchro-  
nous solutions, while simplifying the design relative to  
discrete controller solutions. In addition to simplifying  
the design, the integrated MOSFETs minimize EMI,  
reduce board space, and provide higher reliability by  
minimizing the number of external components.

Ordering Information  
The MAX15041 also features thermal shutdown and  
overcurrent protection (high-side sourcing and low-side  
sinking), and an internal 5V LDO with undervoltage  
lockout. In addition, this device ensures safe startup  
when powering into a prebiased output.
