TPS40054PWPG4 is an advanced, high-performance DC-DC converter integrated circuit (IC) with adjustable current limit and Power-Good feature. It is designed to provide high efficiency, low core power dissipation, and low output voltage ripple in a wide range of applications. The TPS40054PWPG4 features an adjustable low-voltage (1.5 V), wide input voltage range (3.3 V–68 V), high-efficiency (+/–3%), and low-maintenance design with over-current protection, over-temperature protection, and hot-plug control.

TPS40054PWPG4 has a number of application fields. It is used in a variety of solar, renewable energy, and industrial applications such as DC-DC bus converters, power converters, voltage regulators, LED drivers, LED backlighting, battery chargers, and portable power supply systems. It is also used in intermediate bus converters and can be integrated into booster stage of voltage converters.

The TPS40054PWPG4 works on a switched-mode power supply (SMPS) topology with two N-channel MOSFETs operating as a buck converter. The TPS40054PWPG4 monitors the output and is designed to respond to rising output current. It provides an adjustable current limit by sensing voltage drop across an external sense resistor between the drain of the low-side switch and ground. If the output current exceeds the current limit, the MOSFETs are disabled and a short circuit event is registered in the current limit fault flag. The TPS40054PWPG4 provides soft-start and adjustable hiccup mode as well as power-good flag and soft-stop features.

The TPS40054PWPG4 utilizes a wide input voltage range and high peak efficiency up to +/–3%. It operates with a low input current and has enhanced thermal protection that incorporates a programmable over-current shutdown protection and over-temperature shutdown protection. The device is easy to configure and is versatile enough to address a wide range of solar, renewable energy, and industrial applications.

In conclusion, TPS40054PWPG4 is a high-performance DC-DC converter integrated circuit (IC) with adjustable current limit and Power-Good feature. Its application fields include DC-DC bus converters, power converters, voltage regulators, LED drivers, LED backlighting, battery chargers, and portable power supply systems. It works on an SMPS topology with two N-channel MOSFETs to provide an adjustable current limit, and has enhanced thermal protection. It also provides an adjustable hiccup mode and power-good flag as well as soft-start and soft-stop features.
