Product Features:
Module uses high-quality LM2577 chip, high efficiency (up to 92%), heat a small can go to 15W, not added to the radiator, the radiator can go to 20W output power
The module with low ESR the original Sanyo filtering capacitor, the output ripple more specifically want to add an LC filter circuit at the output, you can reduce the ripple voltage as low as 50mV (output voltage of 24V, 12V 20mV or less), suitable for most occasions.
This module uses the machine placement, reflow soldering, each module before shipment After two hours of burn-in test to ensure high reliability.
