TEA1611T - Circuito Integrado SOIC20

Zero voltage switching resonant converter controller

The TEA1611T is a monolithic integrated circuit implemented in a high voltage DiffusionMetal Oxide Semiconductor (DMOS) process, which is a high voltage controller for a zerovoltage switching resonant converter. The IC provides the drive function for two discretepower MOSFETs in a half-bridge configuration. It also includes a level-shift circuit, anoscillator with accurately programmable frequency range, a latched shut-down functionand a transconductance error amplifier.To guarantee an accurate 50 % switching duty factor, the oscillator signal passes througha 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 mainsvoltages
