Suggested capacitor CHEMI-CON KY 330μF/100V. 5 That “natural convection” is about 20LFM but is not equal to still air (0 LFM). 6 With a input capacitor 22μF/50V for input voltage >28VDC, the input voltage allows 32VDC, max. 7 Input voltage must be higher than output voltage set:>1.5V for 3.3V~5V and >3V for 6.5V~15V. 8 Specifications are subject to change without notice.

Test Setup Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47μF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm and 75 mm from the DC/DC Converter. +Out GND +Vin Switching Regulator Resistive LoadScope Copper Strip Cout Copper Strip DC Power Source Technical Notes Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3μF capacitors at the output. +Vin +Out GND Load DC Power Source Cout Switching Regulator Maximum Capacitive Load The M78SA series has limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found in the data sheet.
