TPS40055PWP Application Field and Working Principle
The TPS40055PWP is a non-synchronous buck topology controller manufactured by Texas Instruments. It is an application-specific integrated circuit (ASIC) which is designed to control buck voltage regulators. It integrates high-side and low-side drivers, as well as speed and current sensing. The TPS40055PWP is suitable for a wide variety of applications, including computing, consumer devices, and automotive applications.
The TPS40055PWP is part of TI’s family of integrated buck controllers, which are designed for AC/DC and DC/DC power converters. It is able to control buck converter topologies and provide power stage protection, current foldback slew rate control, scalable high-side low-side gate current, and programmable peak current level. In addition, it provides an integrated power good signal.
The TPS40055PWP operates as a DC-DC converter from a 2.5 V to 28 V input supply to provide a variable output voltage from 0.6 V to the input voltage. It is able to maintain a constant output power. The converter operates by switching between high and low side MOSFETs at a given frequency. The switching frequency can be programmed between 600 kHz and 1.14 MHz and can be synchronized with an external clock. The external clock is used to provide synchronization and accurate frequency control.
The TPS40055PWP also integrates a programmable soft-start feature, which helps in reducing the inrush current and thus avoids sound issues and voltage deviation. The TPS40055PWP also provides PLL synchronization, adjustable current limit peak detection, and adjustable dead-time. It is able to detect over-current and over-voltage conditions and the status registers are available to read back the fault data. It also includes short pin protection and short-circuit protection.
The TPS40055PWP is widely used in a variety of applications. It can be used in notebooks, desktops, server applications, and telecommunication platforms. It is also used in industrial applications, as well as automotive applications. It can also be used in power management IC (PMIC) applications, such as voltage regulators and DC-DC switching controllers.
