The TPS62243DRVT is a DC/DC switching regulator that is specifically designed as an adjustable 3A (maximum) step-up converter with integrated power FET. It is part of the PMIC – Voltage Regulators – DC DC Switching Regulators category, being a very efficient and dependable voltage regulator when it comes to providing a stable output.

Although designed as a five-pin adjustable regulator, the TPS62243DRVT also utilizes a fixed 2.5V output voltage. Its input voltage range reaches from 4V to 20V, which guarantees a durable and reliable power supply. The device features a wide PWM frequency range (50kHz to 500kHz adjustable) that allows the designer to select the optimal frequency for the intended application.

The device has a low quiescent current of only 5µA when it is in shutdown mode. This ensures that the battery life is extended as long as possible, thus providing the user with febled battery consumption. When a load is connected, the quiescent current increases slightly, but this is still very low compared to other power controllers with equivalent output power. Moreover, due to its high switching frequency, the TPS62243DRVT is able to efficiently increase the conversion efficiency in the whole operating temperature range, from -40°C to +125°C.

In addition, its low impedance power switch provides for excellent load and line regulation. The device also features both current-mode and voltage-mode control architectures, thus providing flexibility for the system designer to adjust for optimal performance. Furthermore, its current-mode architecture also provides protection to the device from fault situations such as open-loop, short-circuit, and over-voltage, thus making the TPS62243DRVT the ideal choice for numerous applications in need of reliable and protected power.

The TPS62243DRVT has been designed for applications such as tracking power, low voltage supply chains and point-of-load regulation, test and measurement systems, LED lighting, medical equipment, cellular base station supply, automotive electronics and transport equipment. Among these applications, the most common use is found in Automotive, where the TPS62243DRVT has a wide variety of applications, including load dump protection, load-shedding, logic supply and power sequencing/inrush current control systems.

Overall, the TPS62243DRVT is a great choice for system designers looking for a power controller that can efficiently handle current and voltage levels. Its high PWM frequency, wide temperature range and low quiescent current provide it with unique features and make it one of the top-rated DC/DC switching regulator for many demanding applications.
