BM1C101F-GE2

Overview

The BM1C101F-GE2 is a Power Factor Correction (PFC) and Quasi-Resonant DC/DC converter IC manufactured by ROHM Semiconductor. It integrates PFC control with a QR flyback controller in a single SOP-18 package. The device supports an input voltage range of 8.9 V to 26 V and operates at a maximum switching frequency of 120 kHz. Key electrical features include integrated soft start, under-voltage lockout (UVLO), thermal shutdown, and a latch BR pin for protection. It functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates PFC and quasi-resonant DC/DC conversion functions into a single chip
• Includes built-in high-voltage tolerance start circuit
• Provides comprehensive protection via UVLO, thermal shutdown, and external latch terminal

Applications

• Power factor correction circuits
• Quasi-resonant DC/DC converter designs
• AC/DC power supply systems

Procurement Notes

Verify the current lifecycle status before procurement, as documentation indicates this part may be marked as Not Recommended for New Designs (NRND).
