BD7690FJ-E2

Overview

The BD7690FJ-E2 is a Power Factor Correction (PFC) controller IC manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10V to 26V and supports a switching frequency up to 220kHz. The device is designed for Boundary Conduction Mode (BCM) control to improve power factor in AC/DC conversion systems. It features a low operating supply current of 65µA, enhancing energy efficiency during standby or light load conditions. The component is housed in an SOP-J8 surface-mount package, suitable for compact electronic designs.

• Implements Boundary Conduction Mode (BCM) control strategy for efficient power factor correction
• Optimized for AC/DC power supplies requiring improved power factor performance
• Low quiescent supply current design reduces overall system power consumption

Applications

• AC/DC power supply units
• Consumer electronics with power factor improvement requirements
• General-purpose switched-mode power supplies

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's official datasheet to confirm compliance with RoHS directives and lead time specifications. Ensure the ordering information matches the exact part number variant required for your Bill of Materials. Cross-reference the SOP-J8 package dimensions with your PCB footprint library before finalizing procurement orders.

Selection Notes

Select this component when designing AC/DC converters that require BCM PFC control within a 10V to 26V input range. Consider its 220kHz maximum switching frequency and 65µA supply current for applications prioritizing efficiency and cost-effectiveness. Verify thermal management requirements for the SOP-J8 package based on the expected power dissipation in your specific circuit topology.

Part Context

This part belongs to ROHM Semiconductor's Power Factor Correction controller family. It is specifically engineered for standard PFC applications where boundary conduction mode offers a balance between performance and complexity. The BD7690FJ-E2 serves as a solution for systems needing to meet regulatory power factor standards without the complexity of continuous conduction mode controllers.
