Power management and switching
STMicroelectronics
The EVLVIPGAN100PD from STMicroelectronics is a 100 W USB Power Delivery (PD) 3.0 reference design for a USB Type-C® power adapter.Â
It is an isolated power supply with a stand-alone USB PD controller. The evaluation board implements, at the primary side, a quasi-resonant flyback converter based on the ST VIPERGAN100, high-voltage flyback converter with optocoupler feedback for voltage regulation and a high-voltage gallium nitride (GaN) power switch.Â
The converter combines a high-performance, low-voltage PWM controller chip with a 650 V start-up cell in a single package. The reference design achieves low standby power consumption thanks to the VIPERGAN100’s advanced power management and low quiescent current.Â
To reduce the input mains current distortion, a power factor correction circuit based on the L6564 controller IC is used. At the secondary side, to increase system efficiency, rectification is based on the SRK1001 adaptive synchronous rectification controller.
The reference design also includes an STUSB4761 controller, which offers the benefits of a full hardware USB PD stack, allowing for robust, deterministic, and safe negotiation in line with USB PD standards.

The STEVAL-A6983CV1 from STMicroelectronics is an evaluation board for testing the performance of the A6983C automotive-grade synchronous monolithic step-down regulators. The A6983C regulators are optimized for low power consumption in light-load mode. Â
STMicroelectronics
The EVLSTGAP3S6S is a half-bridge evaluation board for evaluating the STGAP3S6S isolated single gate driver from STMicroelectronics.
The STGAP3S6S features a maximum 6 A current capability, rail-to-rail outputs, and optimized under-voltage lockout and desaturation protection thresholds for silicon carbide (SiC) MOSFETS. It is ideal for use in high-power industrial motor drivers.
The gate driver has a single Output pin and a driver line for an external Miller clamp N-channel MOSFET: this optimizes the suppression of positive and negative gate spikes during fast commutations in half-bridge topologies.
Device protection features are connected to the recommended network on the board and can be easily evaluated through the board test points. Dual Input pins allow the selection of signal-polarity control and hardware interlocking protection to avoid cross-conduction in case of controller malfunction.
The gate driver allows negative gate driving, and the onboard isolated dc-dc converters provide an optimized drive voltage for SiC MOSFETs.
Renesas
The RTK-251-SinkCharger-RAA489118 from Renesas is a single-port reference design for implementing battery systems with from two to seven lithium-ion battery cells connected in series. It supports two modes: in one, power is supplied solely from the USB Type-C® port; in the other, it enables a power bank function in combination with a li-ion battery with a battery management system (BMS).
Due to losses in the cable, onboard charger, and board, the USB Power Delivery (PD) controller requires appropriate USB Type-C input levels from the USB Type-C source device to operate the battery system effectively. Switches on this evaluation board allow the selection of the number of batteries in series and the charging current.
The firmware for this evaluation board is generated using an instruction tool called VIDWriter.
STMicroelectronics
STMicroelectronics has implemented a simple and innovative ac-dc front-end circuit which enables the designer to perform inrush current limitation in any converter that has an input rectifier bridge topology.
