Power and Energy
USB Type-C™ and Power Delivery: Flexible and robust solutions for certified source and sink
One cable to rule them all
Today, an increasing number of devices and applications are adopting USB Type-C connectors for many good reasons:
- With reversible plugs, it can be plugged into a device both sides of the cable;
- Can carry up to 100W of charging power (from 5V/0.5A up to 20V/5.0A);
- t merges both legacy Type-A and -B functions in a single port and can even change roles on the fly.
Next-Gen Products Targeting Newer Applications
ST POWER DEVICES
GaN Family – VIPerGaN50 / MasterGaN1 and ST-One Devices
The VIPERGAN50 is a high voltage converter, designed for medium power quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters, capable to provide an output power up to 50 W in wide range. It integrates a complete set of features that provide an extremely flexible and easy to use chip and helps to design a highly efficient offline power supply.
The advanced power management with the low quiescent helps to achieve low stand-by consumptions. The feed-forward compensation minimizes the maximum output peak power variation over the entire input voltage range.
The MASTERGAN1 is an advanced power system-in-package integrating a gate driver and two enhancement mode GaN transistors in half‑bridge configuration. The integrated power GaNs have RDS(ON) of 150 mΩ and 650 V drain‑source breakdown voltage, while the high side of the embedded gate driver can be easily supplied by the integrated bootstrap diode. The MASTERGAN1 features UVLO protection on both the lower and upper driving sections, preventing the power switches from operating in low efficiency or dangerous conditions. The interlocking function avoids cross-conduction conditions. The device is available in a compact 9 x 9 mm QFN package.
The ST-ONE is the world’s first digital controller embedding an Arm® Cortex® M0+ core, an offline programmable controller with synchronous rectification, and USB PD PHY in a single package. It is designed to control ZVS non-complementary active clamp flyback converters to create high-power density chargers and adapters with USB-PD interface. By using a novel non-complementary control technique and specifically designed power modes the device allows to reach both high efficiency and low no load power consumption.
