NXP TEA1720A | Demoboard UM10834

Description

The TEA1720BT demo board is a slim line sized and cost effective solution for a 10.6 W USB smartphone charger, USB wireless charger or any low power adapter solution.This user manual describes the TEA1720ADB1132 10 W ConstantVoltage/Constant Current (CV/CC) universal input power supply for tabletadapters/chargers. This demo board is based on the GreenChip SmartPower TEA1720B3T and the TEA1705 transient controller. TheTEA1720B3T and TEA1705 application enables a no-load powerconsumption of less than 20 mW and a low external component count forcost-effective applications. In addition, the TEA1720B3T providesadvanced control modes for optimal performance. The TEA1705 transientcontroller continuously monitors the output voltage. When the outputvoltage drops below the detection level Vdet (VCC), a transient interruptsignal is generated to wake up the TEA1720B3T.
