Low-Cost Voltage-Mode PWM  
Step-Down Controllers  
General Description  
Features  
The MAX1966/MAX1967 are voltage-mode pulse-width-  
modulated (PWM), step-down DC-DC controllers that  
are ideal for a variety of cost-sensitive applications.  
They drive low-cost N-MOSFETs for both the high-side  
switch and synchronous rectifier and require no external  
Schottky power diode or current-sense resistor. Short-  
circuit and current-limit protection is provided by sens-  
ing the drain-to-source voltage on the low-side FET.  
Both devices can supply outputs as low as 0.8V and are  
well suited for DSP cores and other low-voltage logic.

2.7V to 5.5V Input Range (MAX1966)  
2.7V to 28V Input Range (MAX1967)  
0.8V Feedback for Low-Voltage Outputs  
The MAX1966 has an input range of 2.7V to 5.5V while  
the MAX1967 has an input range of 2.7V to 28V. In  
ultra-low-cost designs, the MAX1966/MAX1967 can  
provide efficiency exceeding 90% and can achieve  
95% efficiency with optimized component selection.  
100kHz Switching Frequency Accommodates  
Low-Cost Components  
Thermal Shutdown  
The MAX1966/MAX1967 operate at 100kHz and ac-  
commodate aluminum electrolytic capacitors and pow-  
dered-iron core magnetics in minimum-cost designs.  
They also provide excellent performance with high-per-  
formance surface-mount components. The MAX1966 is  
available in a low-cost 8-pin SO package. The MAX1967  
is available in a 10-pin µMAX package.
