Description
The MAX638 is a step-down switching regulator designed for low-power, DC-DC conversion with minimal components. It typically requires only an inductor, output filter capacitor, and catch diode. The device includes on-chip low battery detection circuitry.
Features
Fixed 5V output
Adjustable output with two resistors
Low operating current
85% typical efficiency
8-pin plastic DIP and narrow SO packages
Three external components
Low battery detector
Applications
Efficient DC-DC step-down regulation
Linear voltage regulator replacement
Battery life extension
Portable instruments
12V to 5V conversion
