The TC1301A-ADAVUA (hereafter referred to as TC1301A) is a linear voltage regulator that is part of Texas Instruments\' Power Management Integrated Circuit (PMIC) family. It is a microcontroller-based single-phase digital voltage regulator that is well-suited to a variety of applications such as AC and DC digital power supplies. This article will explain the application fields and working principles of the TC1301A.
The TC1301A is specifically designed for applications where high efficiency, power factor correction (PFC) and power save mode (PSM) operation are required. It provides highly accurate voltage regulation, with a maximum output voltage accuracy of ±2%, and a maximum line regulation of ±1%. It also provides high efficiency, with a typical efficiency of up to 94%. Additionally, the TC1301A is designed for low external component count and low EMI and RFI noise levels, making it suitable for applications where high reliability and minimal external noise generation are required.
The TC1301A can be used in a variety of application fields, including AC/DC digital power supplies, renewable energy applications, and automotive power supplies. In AC/DC digital power supplies, the TC1301A provides high efficiency, tightly regulated output voltage, and low EMI and RFI noise levels, making it ideal for use in cost-sensitive applications. In renewable energy applications, the TC1301A offers a high efficiency, accurate and reliable voltage regulation, making it suitable for solar energy and wind energy applications. In automotive applications, the TC1301A offers a high efficiency, low EMI and minimal external noise generation, making it an excellent choice for automotive switching power supplies.
The working principle of the TC1301A is based on voltage feedback loop control and power factor correction (PFC). In voltage feedback loop control, the chip continuously monitors the output voltage and compares it to the target voltage, then adjusts the power components to keep the output voltage within the set parameters. In PFC, the chip uses a boost regulator to improve the power factor by increasing the current waveform’s angle of rotation. The chip then uses a synchronous rectifier to reduce the losses associated with the supply line. Additionally, the chip can operate in power save mode (PSM), which reduces the power consumption of applications by automatically switching the chip to standby mode at certain conditions. The chip can also operate in pulse width modulation (PWM) mode, which reduces the output voltage switching ripple and improves the dynamic response of the circuit.
In summary, the TC1301A is a linear voltage regulator that is part of Texas Instruments\' Power Management Integrated Circuit (PMIC) family. It is specifically designed for applications where high efficiency, power factor correction (PFC) and power save mode (PSM) operation are required, and can be used in a variety of application fields, such as AC/DC digital power supplies, renewable energy applications, and automotive power supplies. Its working principle is based on voltage feedback loop control and power factor correction (PFC).
