The TPS40055PWPR is an integrated circuit (IC) component manufactured by Texas Instruments. It is a synchronous buck controller with built-in features for easy implementation of switch mode power supplies (SMPS). This IC is designed to operate in a wide input voltage range, making it suitable for a broad range of applications.
One of the key features of the TPS40055PWPR is its high integration level. It combines the control, gate drive, and protection circuitry into a single device, simplifying the design process and reducing the need for external components. This integration saves valuable board space and reduces the overall complexity of the power supply design.
The device supports an input voltage range from 6V to 55V, enabling it to operate with a variety of input sources, such as automotive batteries or industrial power systems. The output voltage can be adjusted from 0.8V to 85% of the input voltage, providing flexibility for different load requirements.
The TPS40055PWPR incorporates a current mode control architecture, which allows for fast transient response and excellent loop stability. It also features a programmable switching frequency that can be set from 100kHz to 600kHz, enabling optimization for efficiency or size.
Another notable feature is its wide range of protection mechanisms. It includes overvoltage protection, undervoltage lockout, overcurrent protection, and thermal shutdown
