PRODUCT OVERVIEW
The MINMAX M78A 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
regulators come in a package which fits in the standard TO-220 footprint of linear regulators.
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 M78A 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.
