Programmable buck converter for USB PD

24 November 2021 Power Electronics / Power Management

Featuring a synchronous topology for optimum efficiency, the STMicroelectronics STPD01 DC/DC buck converter is digitally programmable for USB Power Delivery (PD) applications up to 60 W.

With a wide input-voltage range of 6 V to 26,4 V, the STPD01 offers flexibility to address applications such as AC multiport adaptors, USB hubs, PC monitors and smart televisions. The output voltage, set via I2C, can be adjusted from 3 V to 20 V in 20 mV 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 all help ensure a robust and safe system.

ST has also launched the STEVAL-2STPD01 USB Type-C PD dual-port adaptor 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 on-board, and the associated software package, STSW-2STPD01, contains a sample application to run on the STM32G07 microcontroller.
