Power Distribution and Topology Distribution in the PD Fast Charging Market

USB PD 3.0 Standard Definition for Power Output Voltage and Power Specifications:
- The power output voltage levels are 5V, 9V, 12V, and 20V, with a maximum allowable current of 3A.
- The maximum current level can be increased to 5A, but this requires the use of a special cable with electrical markers to ensure safety.
Power Distribution and Topology Distribution of PD Fast Charging Power Suppl


Topology distribution of PD fast charging power sources

Mainstream USB PD power is 65W, and mainstream power topology is Quasi-Resonant (QR) Flyback.
PD Fast Charging: Typical Application Circuit of QR Resonant Flyback

Opportunity 1: PROSEMI 2410 LC series brick fuse;
Figure 1: USB PD fast charging circuit schematic.
Opportunity 2: PROSEMI TSS + MOV composite device PLDxxxP102.
Opportunities 3 & 4: For low power below 20W, PROSEMI mainly promotes MSR12. For wave soldering processes, PROSEMI LMJ12 is recommended. Currently, both are widely used in charger manufacturing. However, the LMJ series offers a much wider resistance range, up to 200mΩ.
