Product overview

Description

The STPD01 is a programmable synchronous buck converter suitable to provide power supply in applications following USB power delivery specifications.

The device provides those voltages required by USB power delivery systems as stated in USB PD 3.0 spec up to 60 W output power (20 V, 3 A).

The different levels of output voltage and current limitation can be set dynamically through I2C interface.

Overvoltage, overcurrent and overtemperature protections are included in the device.

A programmable watchdog improves the robustness and the safety of the complete system.

Finally, the device is available in QFN24L 3 x 4 mm2 .
