【USB Hub Evaluation Board Solution】

Renesas Electronics offers a comprehensive product line in the USB hub controller domain, spanning from traditional USB 2.0 to the latest USB 3.0 standard, catering to diverse bandwidth and power consumption requirements. These controller chips are presented via dedicated evaluation boards, enabling developers to rapidly validate the feasibility of their system designs. Renesas' USB hub controllers support single-supply operation (typically 5V) and incorporate integrated voltage regulators, enabling low-power operation – a critical feature for portable devices.

Renesas' USB hub controllers are categorised across several technical tiers: USB 3.0 hub controllers comply with the USB 3.0 standard, delivering ultra-high-speed data transfer rates of up to 5Gbps; USB 2.0 hub controllers support high-speed transfer at 480Mbps and are compatible with the PCI 1.1 specification, functioning as standalone hub devices or integrated solutions.

【USB-C PD Evaluation Board Series Detailed Analysis】

USB Power Delivery (PD) technology has revolutionised device charging and data transfer. Through intelligent negotiation mechanisms, it enables devices to obtain optimal power levels according to their requirements. Renesas' evaluation board portfolio in this domain spans a power range from 140W to 240W, catering to diverse applications from mobile devices to industrial tools. The core value of these evaluation boards lies in providing complete reference designs encompassing critical functions such as power management, protocol negotiation, and safety protection.

Renesas' high-power USB-C PD evaluation boards comprise two primary models: RTKA489EPRDK0000BU (240W) and RTKA489EPRDK0010BU (140W). Both boards support 2 to 7-cell lithium-ion battery series configurations and employ advanced 3-level DC/DC buck controller technology, significantly reducing thermal output and bill-of-materials (BoM) costs.

A standout feature of these evaluation boards is their integrated voltage compensation mechanism, which automatically adjusts the USB Type-C input level to compensate for losses in cables, on-board chargers, and the circuit board itself, ensuring optimal battery charging performance.

【USB Fast Charger Evaluation Board Solutions】

As mobile device battery capacities continue to increase, fast charging technology has become a critical element of user experience. Renesas Electronics offers diverse solutions for rapid charger evaluation boards, covering the full spectrum of requirements from basic buck-boost chargers to advanced multi-battery management systems (BMS). These evaluation boards not only support the latest USB-C PD 3.0 standard but also comply with the Programmable Power Supply (PPS) protocol. This enables dynamic adjustment of voltage and current based on the device battery's real-time status, achieving an optimised charging curve.

The RTKA489110DE0000BU evaluation board demonstrates the exceptional performance of the RAA489110 buck-boost charger. This chip employs Renesas' proprietary R3™ technology to deliver high light-load efficiency and rapid transient response. This evaluation board supports 2- to 4-cell lithium-ion battery configurations with a wide input voltage range of 4V to 30V, compatible with diverse power sources including conventional AC/DC adapters, USB PD ports, and travel adapters. Its core technical advantage lies in seamless DCM/CCM switching, ensuring high efficiency across the entire load range.
