Love Tomb Style No. 624 - 12V10A step-down in MK9218 atmosphere

Overview

Input voltage: designed for 13-25V

The output voltage is constant 12V

Output current maximum 10A

The model is MK9218CQB, which can replace LM5145 (P2P)

Relatively strong, with a driving current of more than 2A

We don’t have such a high-power power supply for the time being, so let’s make do with it first. The working temperature is estimated to be around 45° at this time.

I got this chip from their first-level agent. I added WeChat and the communication was very pleasant. The agent also sent me his test pictures.
