Overview
The BM1P062FJ-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 utilizes a flyback topology. The device features an internal switching element, eliminating the need for external power switches. Key electrical specifications include a maximum duty cycle of 75% and a fixed switching frequency. Designed for surface-mount installation, it is housed in an 8-SOPJ package. The component supports both isolated and non-isolated configurations, making it suitable for various AC/DC conversion applications requiring compact power management solutions.
Feature Summary
- Integrates PWM control logic with an internal high-voltage switching transistor for simplified circuit design
- Supports flyback topology for efficient AC/DC power conversion
- Provides stable operation across a wide input voltage range without external gate drive components
Applications
- AC/DC power supply modules
- Offline DC/DC converters
- General-purpose power management systems
Procurement Notes
Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the SOPJ-8 footprint matches your PCB layout requirements. Confirm that the flyback topology aligns with your transformer selection and isolation voltage needs before finalizing procurement.
Selection Notes
Select this component when a compact, integrated solution for flyback conversion is required. It is appropriate for designs needing an internal switch to reduce bill of materials count. Consider the 8.9 V to 26 V input range and 75% duty cycle limits to ensure they meet your specific voltage regulation and load requirements.
Part Context
This part belongs to ROHM's family of PWM control type DC/DC converter ICs. It is functionally similar to other models like the BM1P066FJ-E2 but may differ in specific timing parameters or internal switch ratings. These ICs are designed to replace discrete controller and MOSFET combinations in space-constrained power supplies.
Replacement Considerations
The BM1P062FJ is listed as an alias for this part number. Verify if the BM1P066FJ-E2 serves as a direct functional substitute in your specific application, noting potential differences in switching frequency or duty cycle characteristics.
