TEA1610T集成電路（IC）的電源控制器監(jiān)視器規(guī)格書PDF中文資料

General description

The TEA1610 is a monolithic integrated circuit implemented in a high-voltage Diffusion Metal Oxide Semiconductor (DMOS) process. The circuit is a high voltage controller for a zero-voltage switching resonant converter. The IC provides the drive function for two discrete power MOSFETs in a half-bridge configuration. It also includes a level-shift circuit, an oscillator with accurately-programmable frequency range, a latched shut-down function and a transconductance error amplifier.

To guarantee an accurate 50 switching duty factor, the oscillator signal passes through a divide-by-two flip-flop before being fed to the output drivers.

The circuit is very flexible and enables a broad range of applications for different mains voltages.
