Its flyback topology suits auxiliary and bias supplies in industrial, appliance, and IoT applications where galvanic isolation between primary and secondary is required (Output Isolation: Isolated). ## 28 V startup, 2.7-32 V supply range The controller starts from a 28 V startup threshold and operates across a 2.7 V to 32 V Vcc/Vdd range, giving the bias winding design flexibility for different output power levels. On-chip fault protection includes over-voltage and short-circuit detection, reducing external component count in the primary-side sense circuit. ## 8-SOP package, -40 to 105 °C range The -40 °C to 105 °C operating temperature range covers industrial and outdoor-rated equipment without requiring a heatsink at typical bias supply power levels. ## Active lifecycle, RoHS3 compliant ROHS3 compliant, it meets the latest EU restriction directive for lead and other hazardous substances in electronic equipment.","metaTitle":"ROHM BM1R00149F-E2 Flyback Controller, 8-SOP, Active","metaDescription":"ROHM BM1R00149F-E2 offline flyback controller IC in 8-SOP package.
