PRODUCT OVERVIEW
The MINMAX M78SA series is a new range of switching regulators designed as a drop-in replacement for old LM78xx linear regulators with low
efficiency.The very high efficiency of these step-down converters allow an operating temperature up to 80°C at full-load without need of any heatsink.
The high efficiency and low stand-by power consumption of these switching regulators offer the designer a new, cost-efficient solution for many applications.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.
Other input and output voltage may be available, please contact factory.
We recommend to protect the converter by a slow blow fuse in the input supply line.
The M78SA series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor CHEMI-CON KY 330µF/100V.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
With a input capacitor 22µF/50V for input voltage >28VDC, the input voltage allows 32VDC, max.
Specifications are subject to change without notice.
Input voltage must be higher than output voltage set:>1.5V for 3.3V~5V and >3V for 6.5V~15V.
