General description

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.

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.

Features

Distinctive features

■ Universal mains supply operation, 70 VAC to 276 VAC.

■ High level of integration, resulting in a very low external component count.

■ Fixed frequency operation.

Green features

■ Cycle skipping mode at very low loads; input power < 300 mW at no-load operation for

a typical adapter application.

■ On-chip start-up current source.

Protection features

■ 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.

TEA1530AP屬于集成電路（IC） > AC DC 轉(zhuǎn)換器，離線開關(guān)。恩智浦半導(dǎo)體公司制造生產(chǎn)的TEA1530APAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
