Overview

TEA1703TS GreenChip SMPS standby control IC Rev.
1 — 7 June 2012 Product data sheet 1.
General description 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 low1.
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.
