TEA1504 is intended for off-line 90 to 276 V (AC) power supply applications. It is one of a family of high voltage ICs integrating both analog and digital circuit functions for controlling a switched mode power supply (SMPS). Its functions include integrated high voltage start-up current source, voltage Pulse Width Mode (PWM) control, 5% accurate oscillator, band-gap derived reference voltages, comprehensive fault protection and leading edge blanking. Its high level of integration allows power supplies to be cost effective, compact, lightweight,highly efficient, more reliable, and simple to design.Efficient green features permit very low power operation modes, and an innovative on/off function allows an expensive mains switch to be replaced with a low-cost functional switch.
