HUSB361 package schematic
HUSB361 can be pin-to-pin replacement of the same type of products on the market and similar products under Huinengtei, without the need to redesign to improve the performance of PD and quickly complete the upgrading of products.
Design of Single C fast charge based on HUSB361
HUSB361 Single C fast charge reference design small board physical picture
The single-port fast charging source design above can achieve dynamic power reduction and switch between 18W, 20W, 25W, 30W, 45W and 60W via pins. In addition, the HUSB361 has a lower power consumption than its peers, with standby current of 550μA and operating current of 2.6mA.
Dual C fast charge design based on HUSB361
Using two HUSB361, the design scheme of 65W dual C power supply with small size, high reliability and low cost can be realized. This design supports any single C port 65W output power, double port with the two ports each 30W output power; At the same time, it can adjust the output voltage of ACDC. When the output of port C is less than 12V, the front-end output can be adjusted to 13V to supply power to DCDC, improving the conversion efficiency.

Highlights of the scheme
Intelligent power distribution. Typical application: single-port output PD65W, PDO5:5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3.25A; Dual port PD30W at the same time, PDO5:5V/3A, 9V/3A, 12V/2.5A, 15V/2A, 20V/1.5A.
It can be set through PS0 and PS1, and supports other power combinations, such as 20W+45W. 18 w + 45 w; 25W+30W, etc.
The circuit is simple, the total number of devices is small, high cost performance, low difficulty to achieve.
Good EMC performance.
