It is capable of providing regulated output voltages as low as 0.8V with intake voltages up to 13V.

Due to its wide input and output voltage range, the TPS55340PWP can be used in a wide range of applications. It is particularly well-suited for low voltage power supplies and voltage regulation applications, such as system-level power-down, LCD voltage regulation, and automotive sub-system power. It is also suitable for high power factor and high power applications, such as charge pumps, converter supplies and other DC/DCs.

Working Principle

The TPS55340PWP utilizes an integrated control FET to regulate the input voltage to its desired output voltage, using a PWM control IC with high switching frequency. When the input voltage is greater than the output voltage, the control FET switches on, allowing current to flow through the inductor and maintaining the regulated output voltage. When the input voltage is lower than the regulated voltage, the control FET switches off, causing the inductor to charge until the output voltage is reached. This is known as a buck DC/DC converter and is how the TPS55340PWP functions.

For improved efficiency, the TPS55340PWP incorporates a variety of protection circuits, such as thermal shutdown to protect against excessive junction temperatures, low-voltage lockout to prevent low input input voltages, and integrated soft-start for improved system stability. The TPS55340PWP also utilizes an integrated compensation circuit which provides a stable output voltage, even when the load and temperature are changing.

In addition, the TPS55340PWP operates in a very low quiescent current standby mode, enabling greater battery life and improving overall efficiency. This makes the TPS55340PWP an ideal solution for battery-powered and other mobile applications.
