Design tool extends to single chip USB port power supplies
Silanna Semiconductor has extended its Power Density Hero design tool to cover high efficiency, single chip USB port power supply for multi-port fast chargers.
Engineers can now use the Power Density Hero online configuration tool to accelerate the design of multi-port chargers based on Silanna’s SZPL3002A. The device is claimed to be the world’s first buck converter power IC to feature intelligent power sharing.
The SZPL3002A power IC combines a high efficiency synchronous buck converter and a USB PD/FC port controller into a single QFN package measuring 5.0 x 5.0mm. This allows engineers to reduce the number of components needed to implement multi-port fast charger and adapter applications with each port rated for up to 65W output power.
Power sharing and port power re-balancing functionality is available across two, three or four ports. The controller ensures that port power adapts to the needs of a particular device, irrespective of when connections are made.
Silanna Semiconductor’s Power Density Hero online design software tool simplifies and speeds the specification and prototyping of high efficiency custom AC/DC and DC/DC power applications. Adding the SZPL3002A to the devices covered by the tool means registered engineers can use a simple and intuitive interface to enter a variety of key system parameters and performance requirements for target applications built around this IC. For example, engineers can input minimum and maximum input voltage, output types and voltage and controller IC types.
When all of the information has been entered, the tool instantly calculates the necessary electronic components and values and automatically sends a personalised, confidential document with comprehensive design specifications, circuit schematics and an optimised bill of materials (BoM) encompassing all devices, power ICs and discrete components.
Mark Drucker, Silanna Semiconductor’s CEO commented: “The SZPL3002A was developed to dramatically simplify multi-port charger applications. By providing the ability to configure a complete SZPL3002A-based solution using our easy-to-use Power Density Hero tool, we have made the design process even easier, helping OEMs to further minimise prototyping and testing times, make better use of internal resources and accelerate time-to-market for their next-generation products.”
