PMIC - Voltage Regulators - Linear

TC1301B-DPAVMFTR is a linear voltage regulator designed by Texas Instruments (TI) and characterized by excellent electrical performance. The device integrates two buck converters, seven low-dropout linear regulators, two linear current-limiting devices and two short-circuit protection devices, providing a reliable and simple solution for powering different loads with different voltages.

One of the key features of TC1301B-DPAVMFTR is that it is capable of operating with input voltage above, at and below its output voltage, making it suitable for powering many different applications. This feature, combined with its high efficiency, makes it a highly reliable device for a variety of tasks, such as noted below.

Applications

• Automotive systems, such as power steering, speed control and airbag controllers.
• Telecommunications systems, such as cellular phones and wireless LANs.
• Industrial applications, such as motor speed and position controllers.
• Commercial applications, including point-of-sale terminals, barcode scanners and other low-power embedded devices.

The TC1301B-DPAVMFTR also grants small size and increased functionality to designs. This capability, along with its integrated fault-protection devices, makes it highly attractive for space-constrained applications.

Working Principle

The TC1301B-DPAVMFTR is a linear voltage regulator based on the voltage reference voltage (which is the primary input of the device). The device facilitates the monitoring of the output voltage through the voltage divider network, which senses a fraction of the output voltage and feeds it to the ADC. The ADC further converts the voltage in the digital form and compares it with the reference voltage. When the output voltage drifts away from the reference, the PWM module adjusts the duty cycle proportionally so as to maintain the output voltage at the desired value.

In addition, the TC1301B-DPAVMFTR provides short-circuit protection as well as over-current inhibition. Over-current detection is handled by a two-stage process, where the first step reduces the current by reducing the PWM duty cycle. In the event that the output current is still too high, the safety pin is pulled down, disabling turn-on of the output MOSFET. It also includes other features, such as thermal shutdown and under-voltage lockout.

In conclusion, TI’s TC1301B-DPAVMFTR is a linear voltage regulator well suited for a variety of applications and use cases, characterized by high efficiency and reliability, and reputable for its ability to operate at various input and output voltages. Thanks to its integrated fault-protection devices, such as short-circuit protection and over-current inhibition, it is well-suited for powering space-constrained applications.
