BM1P107FJ-E2

AC DC Converters, Offline Switchers Overview

The BM1P107FJ-E2 is a PWM control type DC/DC converter IC manufactured by ROHM Semiconductor. It operates within an input voltage range of 8.9 V to 26 V and provides a fixed output voltage of 12.5 V. The device supports an output current of 1 A with a switching frequency of 100 kHz. It features both isolated and non-isolated configurations, drawing a supply current of 1 mA. The component functions reliably across a temperature range of -40°C to +85°C and is housed in an SOP-8 surface-mount package.

AC DC Converters, Offline Switchers Feature Summary

• Integrates PWM current mode control for precise regulation and fast transient response.
• Supports flexible design through compatibility with both isolated and non-isolated topologies.
• Includes built-in protection mechanisms such as thermal shutdown, under-voltage lockout, and auto-restart capabilities.

AC DC Converters, Offline Switchers Applications

• Non-insulated high-efficiency power converters for consumer electronics
• Power supplies for devices with various connector interfaces
• General-purpose DC/DC conversion systems requiring compact design

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix and revision level against the official ROHM datasheet to ensure electrical compatibility. Confirm that the SOP-8 package dimensions match the target PCB footprint. Check for any recent Product Change Notices (PCNs) that may affect mechanical or material specifications despite unchanged electrical performance.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a fixed 12.5 V output at 1 A is required from an 8.9–26 V input source. It is suitable for designs needing either isolated or non-isolated architectures. Consider its 100 kHz switching frequency and current-mode control for applications prioritizing transient response and bandwidth over ultra-low EMI requirements found in frequency-hopping variants.

AC DC Converters, Offline Switchers Part Context

This part belongs to the BM1P series of PWM control type DC/DC converter ICs designed for low-power systems. It complements other ROHM controllers like the BM1Q series by offering external MOSFET flexibility rather than integrated switches. The series targets general consumer electronics where moderate efficiency and simple topology are preferred.

AC DC Converters, Offline Switchers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with similar ROHM PWM controllers such as the BM1P061FJ-E2 only if input/output parameters and isolation requirements align.
