TEA1703T GreenChip SMPS standby control IC Rev. 2.3 28 April 2011 Product data sheet 1. General description 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 1 optocoupler to be driven with a high peak current while keeping the required power low . The TEA1703Ts typical current consumption is 30 A. In a typical notebook adapter application the TEA1703Ts power consumption is less than 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.
