TEA1703TS/N1,115 NXP

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 1 required power low . The typical current consumption of a TEA1703TS is 30 A. In a typical notebook adapter application, the power consumption of a TEA1703TS is < 0.5 mW. 2. Features and benefits Switched-Mode Power Supply (SMPS) standby controller IC enabling very low power standby operation Large input voltage range (5 V up to 30 V) Very low supply current (30 A) typical Switched-mode optocoupler driver output (NXP Semiconductors patented) Easy application, only 6 pins to connect 3. Applications The device can be used in applications that require a very low power no-load standby. 4. Ordering information Table 1.
