概要
説明
The iW765 integrates a USB power delivery (USB PD) 3.1 interface controller with a synchronous rectifier (SR) controller and USB Type-C® disconnect FETs into one device for low total BOM cost USB PD chargers and travel adapters up to 100W. The smaller package size makes low cost, single-sided PCB designs possible, while maintaining the high USB PD adapter performance.
The device pairs with the iW9860 primary-side controller to create Zero Standby Power 100W USB PD power supplies or the iW9870 primary-side controller for 100W USB PD Zero Standby Power GaN power supplies.
The iW765 supports adaptive SR control and drive for optimal efficiency, along with intelligent low power mode to enable very low no-load power consumption when paired with the iW9860 or iW9870 products. Fully digital voltage compensation eliminates the need for external passive components for loop compensation.
