TEA1936xDB1521 - USB PD 45W mobile charging

Overview

The multi-standard 45W mobile charger implements a power supply design with extremely low standby power consumption. The output voltage is completely stable, extremely efficient, and highly reliable. The NXP chipset used is targeted at mobile and notebook power supplies with power requirements up to 100W. The power supply is easy to design and uses a minimum number of external components.

The TEA1936xDB1521 demonstration board is a derivative of the TEA1936xDB1463 demonstration board. TEA1936xDB1521 uses a different protocol controller (TEA19031), which only supports PD2.0. For evaluation purposes we recommend ordering the TEA1936xDB1463 demo board which supports PD2.0 and QC2.0/3.0.

Multi-standard chargers support the following standards:

· USB PD2.0
