DescriptionGreenChip II SMPS Control IC
The GreenChip II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components.

The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed frequency converter designs for low voltage, high current applications. At low power (standby) levels, the system operates in cycle skipping mode which minimizes the switching losses during standby.

  • Description courte

  • The GreenChip II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components. The (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed frequency converter designs for low voltage, high current applications. At low power (standby) levels, the system operates in cycle skipping mode which minimizes the switching losses during standby. The proprietary high voltage BCD800 process makes direct start-up possible from the rectified universal mains voltage in an effective and green way. A second low voltage BICMOS IC is used for accurate, high speed protection functions and control. The TEA1530(A) enables highly efficient and reliable supplies to be designed easily.

    I Universal mains supply operation, 70 VAC to 276 VAC. I High level of integration, resulting in a very low external component count. I Fixed frequency operation.

    I Cycle skipping mode at very low loads; input power mW at no-load operation for a typical adapter application. I On-chip start-up current source.

    Safe restart mode for system fault conditions. Undervoltage protection (foldback during overload). IC OverTemperature Protection (OTP) (latched). Low and adjustable OverCurrent Protection (OCP) trip level. Soft (re)start. Mains voltage-dependent operation-enabling level. TEA1530AT and TEA1530AP: General purpose input for latched or safe restart protection and timing, e.g. to be used for OverVoltage Protection (OVP), output short circuit protection or system OTP.

    I TEA1530T: General purpose input for latched protection and timing, e.g. to be used for OVP, output short circuit protection or system OTP.

    I Printer & LCD adapters / chargers / supplies. The device can, however, also be used in all applications that demand an efficient and cost-effective solution 65 W.
