Power & Power Management

Overview

Description

The iW760 integrates a USB power delivery (USB PD) 3.0 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. 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 63W USB PD power supplies or the iW9861 primary-side controller for lower total BOM cost 63W USB PD power supplies.

The iW760 supports adaptive SR control and drive for optimal efficiency, along with an intelligent low power mode to enable very low no-load power consumption when paired with the iW986x products. Fully digital voltage compensation eliminates the need for external passive components for loop compensation.
