It integrates current-limiting and over-voltage fault protection, and supports either output isolation configuration. ## Switching frequency and duty cycle Switching at a fixed 65 kHz, the BM1P061FJ- operates at a maximum duty cycle of 75%. The 65 kHz rate is a common sweet spot for flyback transformers in the 10-60 W range — high enough to keep magnetics small, low enough to avoid excessive switching losses in the external MOSFET. ## Supply range and start-up behaviour The controller's Vcc range is 8.9 V to 26 V, with a start-up threshold of 13.5 V. The 13.5 V start-up ensures the bias rail is well above the UVLO before the PWM begins switching, preventing hiccup on a slowly rising bulk capacitor. ## Protection and isolation flexibility On-chip fault protection covers current limiting and over-voltage — enough for basic offline supplies without an external supervisor. The output isolation is configurable as either isolated or non-isolated, so the same controller can serve a flyback with an optocoupler feedback path or a simpler primary-side regulated design.","metaTitle":"ROHM BM1P061FJ-E2 Flyback PWM Controller, 65 kHz, 8-SOP-J","metaDescription":"ROHM BM1P061FJ-E2 offline flyback PWM controller, 65 kHz switching, 8.9-26 V supply, 75% duty cycle, current limiting & OVP.
