SZPL3002A from Silanna Semiconductor is the world’s first buck converter IC to feature intelligent, adaptive power sharing. The SZPL3002A is a high-efficiency, buck converter IC with a built-in USB PD/FC port controller. The IC comes in a compact QFN package measuring just 5 mm x 5 mm. The SZPL3002A has an efficiency of over 98% and offers one fully programmable contract set plus four pre-programmed sets that are chosen with an external resistor value. The IC also features protection features such as power throttling at elevated temperatures. The high-efficiency synchronous buck converter can reduce component count in the circuit and simplifies power sharing design in multi-port fast chargers.
“Silanna Semiconductor is known by our mantra ‘Power Management Re-Imagined’ and this unique Power IC is the world’s first to feature intelligent power sharing using a fully integrated USB-PD controller, MCU and VCONN cable communications protocol within this highly efficient DC/DC buck converter,” said Mark Drucker, CEO of Silanna Semiconductor. “Built using the flexibility of our AnyPort™ architecture, we are delighted with customer reactions which have resulted in a large number of early design wins. We are building a stable number of CO2 Smart Power devices and it is exciting to see our design teams focus on the end-to-end power solutions with complementary DC-DC and AC-DC product families that achieve best-in-class efficiency.”
According to the company, the new SZPL3002A buck converter IC with a built-in USB PD/FC port controller will significantly reduce the number of components needed to implement 65W fast charger and adapter applications with up to four ports. The IC offer full support for USB PD V3.0 Type C interfaces and QC2.0/3.0/4.0/5.0 support for Type A/C connections. Facilitating power sharing and port power re-balancing functionality 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.
Hubie Noto, Silanna Semiconductor’s director of product marketing comments: “Traditional charger PD ports offer a selection of fixed contracts to a device based on available power. These are programmed into the port controller and are based on various voltage and current levels a device might use when connecting. Each port has different power contracts for different power. The SZPL3002A offers one fully programmable contract set plus four pre-programmed sets that are chosen with an external resistor value.”
