New Programmable Buck Converter for USB Power Delivery

The STPD01 is a programmable synchronous buck converter suitable for USB power delivery applications. The device provides those voltages required by USB power delivery systems as per USB PD 3.0 spec up to 60 W output power (20 V, 3 A) and includes the necessary circuitry for cable drop compensation.

Available in QFN24L 3 x 4 mm2, the STPD01 embeds a programmable watchdog to improve the robustness and the safety of the complete system, along with overvoltage, overcurrent and overtemperature protections.

Different values of output voltage and current limitation can be also set dynamically through I2C interface.

38 V 1.5 A / 2 A step-down converters with low quiescent current

The new L6981 and L6982 are  easy -to -use regulators delivering high efficiency capability atacross all loads. The wide input voltage range (3.5 V –- 38V) , makes them also the ideal solution for 24 V industrial bus-powered systems, HVAC power supplyies, battery-powered equipment, decentralized intelligent nodes and always-on devices includinglike smart sensors.

Housed in an SO8 package , the L6981 (1.5 A)  and L6982 (2 A) are also based on a peak current mode architecture with internal compensation, to help reduce the overall size and complexity of the end-product designs.

Evaluation boards are available, to support developers in their designs.



60 V 300 mA step-down converter with 10uA quiescent current

ST’s new L7983 is a compact synchronous buck converter able to satisfy noise-sensitive applications and maximize efficiency at light load thanks to its Low-noise and Low-consumption modes.

With a wide input-voltage range, the L7983 can operate from 12 and 24 V industrial buses with wide safety margins. It is also suitable for battery-powered applications, industrial fail-safe systems, decentralized intelligent nodes, appliances, robotics and precision-sensing applications that leverage the easy-to-use Low-noise mode.

Power supply and converter solution evaluation boards based on the L7983 are also available
