Input Range: Up to 40V  
The MAX727/MAX728/MAX729 are monolithic, bipolar,  
pulse-width modulation (PWM), switch-mode, step-down  
DC-DC regulators. Each is rated at 2A. Very few external  
components are needed for standard operation because  
the power switch, oscillator, feedback, and control circuitry  
are all on-chip. Employing a classic buck topology, these  
regulators perform high-current step-down functions.  
2A On-Chip Power Switch  
Fixed Outputs: 5V (MAX727)  
3.3V (MAX728)  
3V (MAX729)  
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 cur-  
rent limiting to protect against overcurrent faults and short-  
circuit output faults. They also have a wide 8V to 40V input  
range.  
Each regulator is available in a 5-pin TO-220 package.  
These devices have a preset 100kHz oscillator frequency  
and a preset current limit of 2.6A. See the MAX724/  
MAX726 data sheet for more applications information.
