STMicroelectronics' STPD01 is a highly versatile programmable synchronous buck converter specifically designed to meet the power supply requirements of USB power delivery applications. Following the USB PD 3.0 specifications, the STPD01 is capable of delivering up to 60 W output power (20 V, 3 A) to meet the demands of high-power USB devices.
The STPD01 offers the flexibility to dynamically set different levels of output voltage and current limitations through its I²C interface, allowing for easy customization and adaptability to various power delivery scenarios. This programmability enables the device to provide the specific voltages required by USB power delivery systems as stated in the USB PD 3.0 specification.
To ensure the safety and reliability of the power delivery process, the STPD01 incorporates overvoltage, overcurrent, and overtemperature protections. These built-in safeguards protect both the converter itself and the connected devices from potential damage caused by voltage surges, excessive current, and high temperatures.
With its programmability, high output power capability, and comprehensive protection features, the STPD01 from STMicroelectronics is an ideal solution for power supply applications in USB power delivery systems.
