The TEA1533AP/N1,112 standard is a low-cost, high-efficiency power management integrated circuit (PMIC) designed for use in an AC-to-DC (AC/DC) converter or an offline switcher. This device has a wide application range, excellent electrical and thermal performance, and an integrated low-noise oscillation circuit.The TEA1533AP/N1,112 is designed to regulate voltage in an AC/DC converter or offline switcher, as well as provide protection against over-voltage, over-current, and thermal shocks. The device regulates the output voltage, by providing a reference voltage with a precision current limiting feature. The device also has an internal driver capable of driving an external external MOSFET or BJT. The TEA1533AP/N1,112 has a wide range of applications; it is suitable for applications such as line-powered low-power AC/DC converters, auxiliary supply AC/DC converters, and small offline switchers for portable and low-voltage applications.The working principle of the TEA1533AP/N1,112 is based on a DC-DC converter architecture. The device consists of an input stage, a current-mode regulator, a voltage regulation stage, a feedback and control stage, an oscillation and driver stage, and an output stage.In the input stage, the AC input voltage is applied to the device, and is rectified and filtered at the input of the device. The current-mode regulator then regulates the output voltage of the device using a reference current that is provided by the integrated oscillator. The feedback and control stage then monitors the output voltage, and adjusts the reference current to maintain the correct output voltage.The oscillator and driver stage then produces the oscillator signal and drives the external MOSFET or BJT. This oscillator signal also provides the reference current to the current mode regulator, which is then used to control the output voltage of the device. The output stage then regulates the output voltage and delivers power to the connected load. In summary, the TEA1533AP/N1,112 is a low cost, high efficiency PMIC designed to regulate voltage in an AC/DC converter or offline switcher and provide protection against over-voltage, over-current and thermal shocks. The device consists of an input stage, a current-mode regulator, a voltage regulation stage, a feedback and control stage, an oscillation and driver stage, and an output stage. With its wide range of applications, excellent electrical and thermal performance, and integrated oscillation circuit, the TEA1533AP/N1,112 is the ideal choice for powering portable devices.
