_______________Ge n e ra l De s c rip t io n  
___________________________Fe a t u re s  
The MAX724/MAX726 are monolithic, bipolar, pulse-  
width modulation (PWM), switch-mode DC-DC regula-  
tors op timize d for s te p -d own a p p lic a tions . The  
MAX724 is rated at 5A, and the MAX726 at 2A. Few  
external components are needed for standard opera-  
tion because the power switch, oscillator, and control  
circuitry are all on-chip. Employing a classic buck  
topology, these regulators perform high-current step-  
down functions, but can also be configured as invert-  
ers, negative boost converters, or flyback converters.  
♦ Input Range: Up to 40V  
♦ 5A On-Chip Power Switch (MAX724)  
2A On-Chip Power Switch (MAX726)  
♦ Adjustable Output: 2.5V to 35V  
♦ 100kHz Switching Frequency  
♦ Excellent Dynamic Characteristics  
♦ Few External Components  
♦ 8.5mA Quiescent Current  
♦ TO-220 Package  
These regulators have excellent dynamic and transient  
response characteristics, while featuring cycle-by-cycle  
current limiting to protect against overcurrent faults and  
short-circuit output faults. The MAX724/MAX726 also  
have a wide 8V to 40V input range in the buck step-  
down configuration. In inverting and boost configura-  
tions, the input can be as low as 5V.  
The MAX724/MAX726 are available in a 5-pin TO-220  
package. The devices have a preset 100kHz oscillator  
frequency and a preset current limit of 6.5A (MAX724)  
or 2.6A (MAX726).
