The TEA1703T is a low power standby controller IC intended to be used in applications which require an extreme low no-load standby power. The TEA1703T includes circuitry for detecting output voltage, output power and switching. The TEA1703T integrates a switched-mode optocoupler driver, which enables an optocoupler to be driven with a high peak current while keeping the required power low. The TEA1703T’s typical current consumption is 30 μA. In a typical notebook adapter application the TEA1703T’s power consumption is less than 0.5 mW.
