USB PD Adapters
USB PD and Fast Charging
Fast charger protocols such as USB PD are dramatically reducing the charging time for a cellphone from an overnight charge to less than 30 minutes. This makes charging more convenient for the user allowing almost continual access to mobile devices.
USB PD is set to become the new standard for charging mobile devices. The USB PD power capability of up to 100 W will make it possible for the user to employ a single charger for cell-phone, tablet and laptop computer.
PowiGaN is Power Integrations’ internally developed gallium nitride (GaN) technology. PowiGaN switches replace the traditional silicon transistors on the primary side, reducing switching losses and enabling power supplies that are more efficient, smaller and lighter than silicon alternatives. PowiGaN-based ICs achieve up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.
