Featuring a synchronous topology for optimum efficiency, the new STMicroelectronics STPD01 DC/DC buck converter is digitally programmable for USB power-delivery (PD) applications up to 60W.
With a wide input-voltage range of 6 to 26.4V, the STPD01 offers flexibility to address applications such as AC multiport adapters, USB hubs, PC monitors, and smart televisions. The output voltage, set via I2C, can be adjusted from 3 to 20V in 20mV minimum steps to meet PD specifications.
The device incorporates cable-drop compensation with an internal voltage-feedback resistor divider, to ensure the load receives the correct voltage unaffected by losses in copper tracks and the attached output cable.
The STPD01 includes protection against over-voltage, over-current, and over-temperature. Additional built-in features include embedded discharge circuitry, soft-start, under-voltage lockout, and a programmable watchdog timer that help ensure a reliable and safe system.
ST has also launched the STEVAL-2STPD01 USB Type-C Power Delivery dual-port adapter kit to accelerate development of solutions based on the STPD01. Created as an expansion card to be used with the NUCLEO-G071RB STM32 Nucleo-64 development board, the STEVAL-2STPD01 board contains two Type-C ports with two STPD01 programmable buck converters.
Two TCPP02-M18 protection ICs for USB Type-C and PD Source applications are also onboard, and the associated software package, STSW-2STPD01, contains a sample application to run on the STM32G07 microcontroller. The STEVAL-2STPD01 kit is available now at ST’s eStore.
The STPD01 is in production and ready to order now at ST’s eStore, packaged in QFN24L measuring 3 x 4mm.
