TC1301A-FDAVMF application field and working principle

The TC1301A-FDAVMF is a highly integrated voltage regulator from Texas Instruments (TI). It is a member of TI’s family of linear adaptive voltage secured regulators. The product is a member of TI\'s flexible, multi-stage architecture, providing a cost-effective solution for various application requirements such as notebook PCs, servers, and other systems that require a consistent power supply.The TC1301A-FDAVMF is a single 3-phase, voltage mode, adaptive voltage secured (AVS) regulator that provides a fixed-voltage output with dynamic voltage positioning. It is designed to support fast transient application requirements while operating with maximum efficiency, requiring fewer external components than a standard voltage regulator solution. It features an ultra-low power loss, efficient power delivery and an extremely small package size.The advanced features of the TC1301A-FDAVMF include a wide input range, excellent line/load transient response, internal soft start circuitry, overvoltage protection and undervoltage control. The voltage regulation is achieved by an adaptive voltage secured architecture, coupled with a single-stage buck-boost converter that allows the regulator to regulate its output voltage to a stable level regardless of the load current or input voltage. The regulator is capable of providing a wide range of output voltages ranging from 0.4V to 8.4V, with a typical accuracy of ±1.5%.The TC1301A-FDAVMF can be used as a standalone device in custom solutions or as a drop-in regulator for notebook PCs, servers or other systems. It can be used to replace aging 2-stage linear regulators or low efficiency switching power supplies, providing an optimal solution for power management. It is also ideal for applications that require high current output and low quiescent current operation, making it a great choice for use with heat-sensitive components such as microprocessors, voltage regulators, and other integrated circuits.The working principle of the TC1301A-FDAVMF is simple and efficient. It uses a two-phase buck-boost converter to drive the output voltage to the desired level. At the input of the regulator, the voltage is sensed by an internal voltage divider. This voltage is then compared to the reference voltage with the help of an error amplifier, resulting in the necessary corrective action. The output of the error amplifier is then used to regulate the duty cycle of the buck-boost converter, thus providing the required output voltage.In summary, the TC1301A-FDAVMF is an advanced 3-phase, voltage mode, adaptive voltage secured (AVS) regulator from Texas Instruments (TI). It offers a wide input range, excellent line/load transient response, internal soft start circuitry, overvoltage protection and undervoltage control. It is also extremely cost-effective, requires fewer external components than a standard voltage regulator solution, and is suitable for applications that require high current output and low quiescent current operation. The working principle of the TC1301A-FDAVMF is based on a two-phase buck-boost converter that drives the output voltage to the desired level. In addition, the device is ideal for use in custom solutions or as a drop-in regulator in notebook PCs, servers or other systems, making it an excellent choice for power management.
