TPS65145PWP

Power management ICs (PMICs) are specialized integrated circuits that are responsible for providing, monitoring, controlling and optimizing power consumption of electronic systems. Among them, the TPS65145PWP is a PMIC designed to efficiently deliver 3.2A current to a broad range of applications such as automotive head units and displays, tablets, IoT (Internet of Things) and other battery-powered handheld applications.

Application Field of TPS65145PWP

TPS65145PWP is a high-efficiency, high-voltage, wide-input synchronous buck converter with integrated high- and low-side NFETs, low-battery monitoring, intelligent temperature protection, and short-circuit protection.Its Wide Input Range Voltage allows the chip supports 18V to 75V input voltage, the step-down oscillator consumes little power, due to the synchronous rectifiers, the TPS65145PWP reach up to 95.1% of peak efficiency.The chip also provides both high- and low-side NFETs for maximum power efficiency, as well as an adjustable output voltage, output current monitor, and an Australian/New Zealand safety-compliant power protection, making it an ideal choice for many applications.

Working Principle of TPS65145PWP

TPS65145PWP is a switching regulator Control IC with built-in high-side and low-side drivers. This type of IC integrates a precise reference voltage, logic and control, a transconductance amplifier, a precise error amplifier, and a low dropout regulator (LDO) with very low quiescent power consumption. The IC works by sensing a change in the feedback voltage of the system, which is then compared to a reference voltage generated internally. When this voltage exceeds the reference voltage, the IC places high and low side drivers into a OFF condition, stopping the logic and control part of the IC to reset the system. However, when the voltage drops below the reference, the IC kick starts both the high and low side drivers, placing them back into an ON state, thus controlling the output voltage of the system.

Conclusion

TPS65145PWP is a high-efficiency, high-voltage, wide-input synchronous buck converter with integrated high- and low-side NFETs, low-battery monitoring, intelligent temperature protection, and short-circuit protection. It is a well-rounded and highly efficient solution for a variety of power applications, such as automotive head units and displays, tablets, IoT (Internet of Things) and other battery-powered handheld applications. And it works by sensing a change in the feedback voltage of the system, which is then compared to a reference voltage generated internally.
