PMIC (power management integrated circuit), as its name suggests, is used to manage the power supply of a product by providing a variety of voltage regulator solutions. Voltage regulators, with the ultimate goal of stabilizing output voltage, provide the most basic and effective power management solution. DC-DC switching regulators are one of the most commonly used regulators on the market, and TL2575-12IKTTR is one of the most popular DC-DC switching regulators in the market.

TL2575-12IKTTR, with TI’s LO (low output ripple) control system, provides extremely smooth mixed control, which ensures its output voltage functions without drop or overshoot. This regulator features an integrated high-efficiency TOPSwitch™ device, inhibit logic, remote line/load sense, and other exclusive functions such as overvoltage and thermal shutdown. These features make TL2575-12IKTTR ideal for applications such as distributed power architectures, remote sense and 24V input logic isolation.

TL2575-12IKTTR also employs many simplified design features which allows the customers to meet their targeted total enhanced efficiency requirements with minimal design time. It features adjustable frequency, which allows customer to adjust the switch frequency obtaining the maximum efficiency and output filter size. This voltage regulator is also provided with a number of protection mechanisms including overcurrent limit, output overvoltage limit and power-limiting protection.

To find out more about the working principle of TL2575-12IKTTR, it is pertinent to look at the block diagram. The regulator consists of an integrated control, which uses a compensation and an error amplifier for control of output voltage and current. The output is then fed to a NPN and PNP power transistor, which switches between the input voltage and the output secondary voltage, producing an integrated output voltage. The feedback is then fed to the error amplifier, which in turn controls the pulse width of the NPN and PNP transistors in such a manner that the output voltage remains within the specified range.

The TL2575-12IKTTR also incorporates a wide input voltage range (from 4.5V to 25V) and a wide output voltage range (1.25V to 18V), providing the user with flexibility when designing the power solution. In addition, its built-in switching and linear regulators are designed to provide extremely low noise and low power dissipation.

Overall, TL2575-12IKTTR is an ideal voltage switching regulator for distributed power architectures, remote sense, and 24V input logic isolation applications. With virtually no drop or overshoot, its integrated control system ensures its output voltage functions efficiently. It also includes many features, such as overcurrent limit, output overvoltage limit, adjustable frequency and power-limiting protection, which simplifies the design and increases the efficiency for the customer. With its wide range of input and output voltages and its low noise, low power dissipation and high efficiency characteristics, TL2575-12IKTTR is a versatile and reliable solution for many power management applications.
