Abstract TEA1703 is a low power standby controller IC intended for use in SMPS
applications that require an extremely low no-load standby power. The
TEA1703 includes detection circuitry for output voltage, output power and
also switching detection circuitry. The TEA1703 integrates a switched
mode optocoupler driver which makes it possible to drive an optocoupler
with a high peak current, while keeping the required power low.
