TEA1703TS: Secondary side controller enabling very low standby power

The TEA1703TS is a low power standby controller IC intended to be used in applications which require an extreme low no-load standby power. The TEA1703TS includes circuitry for detecting output voltage, output power and switching of the SMPS. The TEA1703TS 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 typical current consumption of a TEA1703TS is 30 μA. In a typical notebook adapter application, the power consumption of a TEA1703TS is < 0.5 mW.
