SY8303 Synchronous Buck DC Verification Board

8303 is a small-sized synchronous buck, which is more suitable for flight control and other situations that require small size, high efficiency, and wide input voltage.

Its voltage of 4.5-40v is suitable for the power supply requirements of 2S-7S. Its programmable frequency can be adapted to different load situations. By configuring the frequency, the sensitive frequency band of flight control communication can be avoided. Inductance calculation can be adapted to most situations. If special circumstances are required, please re- Calculation. I won’t translate it in the manual, just those few words.
