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.

TEA1530AT属于集成电路（IC） > AC DC 转换器，离线开关。恩智浦半导体公司制造生产的TEA1530ATAC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
