25W Automatic Step Up And Step Down Module Solar Power Board 3V 15V To 0.5V 30V

Features:
-The module uses high-quality control chip from Taiwan , and expands ultra-low on-resistance MOSFET. The efficiency is very high (up to 95) . It can reach 25W without heat dissipation.
-This module uses the low- ESR original Sanyo filter capacitor, and the latter stage adds more than one LC filter unit, which can make the ripple voltage as low as 40mV, which can be applied to most occasions!
-This module uses machine patch, reflow soldering, and each module undergoes two hours of aging test before shipment to ensure high reliability.
