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.
Evaluation board is available to support developers in their designs.
STEVAL-2STPD01
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 supplies, battery-powered equipment, decentralized intelligent nodes and always-on devices like 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.
