Introduction
The Texas Instruments TPS64202DBVTG4, a high-performance step-down DC/DC controller with comprehensive features, is a great solution for reducing the development effort and cost of System on Chips (SoCs). It features a single external resistor to set the output current limit, making it ideal for power system designs with limited board space such as PCs, tablet PCs, and other highly integrated platforms.
Features
The TPS64202DBVTG4 offers an adjustable output voltage range from 0.05V to 18V and a 3.3V internal operating voltage. It has an input voltage range from 8V to 40V and offers a programmable switching frequency between 500kHz and 3MHz. It also includes a programmable internal switching waveform, current-mode control with excellent line and load transient response, enable-off control, and a power-save enable (PSE). It also provides an enable-off control to reduce system standby current consumption, as well as an adjustable soft-start control to reduce system start-up time.
Application Field
The TPS64202DBVTG4 is well suited for various portable and low-power applications, such as notebook computers, tablets, and wireless handsets. It is specifically designed for applications that require DC/DC conversion with high efficiency and output current stability. It is also ideal for automotive applications that require long battery life, including vehicle power management, charging and powering systems, and infotainment systems.
Working Principle
The TPS64202DBVTG4 utilizes synchronous current control architecture, which ensures good performance and line/load transient response. It regulates the output current of the switch by controlling the total on-time of the switch. The output current limit is programmed by the external resistor connected to the ILIM pin. The internal switching waveform is adjustable via the VSEN pin, enabling different output voltage settings. The PSE pin is used to enable and disable the controller, and the enable-off control feature can be used to further reduce system standby current consumption. The soft-start control feature can also be used to reduce system start-up time.
Conclusion
The TPS64202DBVTG4 DC/DC switching controller is an efficient, cost-effective solution for System on Chips (SoCs) that require DC/DC conversion with high efficiency and output current stability. Its features such as adjustable output voltage, programmable switching frequency, internal switching waveform, and current-mode control ensure good performance and line/load transient response. It is well suited for various portable and automotive applications. With its comprehensive features, the TPS64202DBVTG4 is an excellent choice for designers that need to reduce the development effort and cost of their power systems.
