Input Range: Up to 30V  
The MAX830/MAX831/MAX832/MAX833 are monolithic,  
bipolar, pulse-width-modulation (PWM), switch-mode, step-  
down DC-DC regulators. Each is rated at 1A. 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.  
1A On-Chip Power Switch  
Adjustable Output (MAX830)  
Fixed Outputs: 5V (MAX831)  
3.3V (MAX832)  
3V (MAX833)  
100kHz Switching Frequency  
Excellent Dynamic Characteristics  
Few External Components  
8mA Quiescent Current  
16-Pin SO 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 have a wide 8V to 30V input  
range. Outputs for the MAX831/MAX832/MAX833 are fixed  
a t 5V/3.3V/3V, re s p e c tive ly. The MAX830 outp ut is  
adjustable.  
Evaluation Kit Available  
Available in 16-pin SO packages, the MAX830–MAX833  
have a preset 100kHz oscillator frequency. In addition,  
the preset current limit and micropower shutdown can be  
externally controlled. See the MAX724/MAX726 data  
sheet for more applications information.
