USB Power Delivery: Fast Role Swap and Programmable Power Supply
USB Power Delivery (USB PD) brings two key features to the table: Fast Role Swap (FRS) and Programmable Power Supply (PPS). These improve how devices manage power and charging.
Fast Role Swap lets devices switch from being a power source to a power sink quickly. This enhances USB charging. For example, a device low on power can become a power sink. It receives power from another source swiftly, with no delay.
FRS allows devices to switch between source and sink behavior without interrupting the charging process.
Programmable Power Supply in USB PD enables tiny changes in voltage and current while charging. This boosts efficiency. PPS means power can be adjusted perfectly for devices, like lithium-ion batteries.
PPS enables small step-wise changes in voltage and current, reducing conversion loss during charging.
These advancements make charging more productive and dependable. FRS and PPS lead to quicker, more suitable charging. This enhances both productivity and convenience for users.
