NXP Semiconductors has launched the GreenChip TEA1733—a low-cost IC that increases energy efficiency and standby performance of power supplies under 75W. Designed for low-power computing and communication applications such as netbook adapters, printer adapter and LCD monitor supplies, the TEA1733 is a switched mode power supply (SMPS) controller IC that enables standby power levels less than 0.1W. The GreenChip TEA1733 is the first of a complete series of low-power AC/DC control ICs to be launched by NXP over the next year.
To enable higher efficiencies at low standby mode and at all load levels, the TEA1733 requires a very low start-up current of 10μA and consumes a low supply current of 1.25mA. The combination of fixed frequency operation at high output power and frequency reduction at low output power provides high efficiency over the total load range. Due to its high level of integration, the TEA1733 enables a compact and lighter power supply design with reduced number of external components in the SMPS. The TEA1733 is available in a safe restart protection version as TEA1733 and also in a latched protection version as TEA1733(L).
