IP2726

The IP2726 monitors the power requirements of devices connected to both ports and dynamically allocates available power. When a single device is connected, it can receive up to 100W. When two devices are connected, the IC intelligently splits power based on each device's capabilities and charging profile. For example, it might allocate 65W to a laptop and 30W to a phone, or 45W to each if both devices support similar power levels. The allocation updates in real-time as device requirements change.

The intelligent allocation optimizes charging for multiple devices. Contact us for detailed power allocation algorithms and configuration options.

Yes, both ports support fast charging simultaneously with intelligent power sharing. The total output power is limited to 100W, so the specific power per port depends on the connected devices and their requirements. Both ports support all major fast charging protocols, ensuring optimal charging performance regardless of device combination.

Both ports support fast charging. Design your power stage to handle the total 100W output with adequate thermal management.

The IP2726 integrates dual-port control with intelligent power management in a single chip, reducing BOM cost and PCB space. Using two IP2723T chips requires external power management logic to coordinate between ports. The IP2726's built-in intelligence ensures optimal power allocation without external MCU intervention. For cost-sensitive designs with limited space, IP2726 is the preferred solution.

Use IP2726 for integrated dual-port solutions. Consider dual IP2723T only if ports need to be physically separated or for specific architectural requirements.

Power allocation can be configured through the I2C interface or external resistors. You can set maximum power limits for each port and define allocation priorities. The IC respects these limits while optimizing power distribution within the constraints. For example, you can limit Port 1 to 65W maximum and Port 2 to 35W, or configure equal 50W limits for both ports.

Configure power limits based on your power stage capabilities and thermal design. Our FAE team can provide configuration guidance.

Yes, the IP2726 supports Dual Role Power (DRP) operation, allowing the port to function as either a source (provider) or sink (consumer). This is useful for applications like power banks that need to both charge internal batteries and power external devices. The IC handles role negotiation automatically through the USB PD protocol.

For DRP applications like power banks, IP2726 provides flexible source/sink operation. Contact us for DRP reference designs.

At 100W total output, thermal management is critical. The IP2726 itself has low power dissipation, but the external power stage components require proper heat sinking. Consider using synchronous rectification for high efficiency, adequate copper area for heat spreading, and thermal vias to inner ground planes. For enclosed designs, ensure sufficient airflow or add thermal management features.
