BD7692FJ-E2

Overview

The BD7692FJ-E2 is a Boundary Current Mode (BCM) Power Factor Correction controller IC manufactured by ROHM Semiconductor. It operates within an input voltage range of 90 VAC to 264 VAC and provides a regulated output of 400 V with a maximum output current of 500 mA. The device supports a maximum output power of 200 W and achieves a typical power factor of 0.97 at 230 VAC input with full load. It functions within an operating temperature range of -10°C to +65°C.

Feature Summary

• Implements Boundary Current Mode (BCM) control method for efficient power factor correction.
• Utilizes Zero Current Detection (ZCD) via a resistor to eliminate the need for auxiliary winding wires, reducing switching losses and electromagnetic interference noise.

Applications

• Power factor correction stages in AC/DC power supplies
• General consumer electronics requiring PFC compliance
• Industrial equipment power systems
