Overview
The BM2P091F-GE2 is a PWM type DC/DC converter IC from ROHM Semiconductor, featuring an integrated 650V switching MOSFET. It operates with a fixed switching frequency of 65 kHz and supports a maximum duty cycle of 82%. The device accepts an input voltage range of 8.9 V to 26 V and delivers an output current of 1.3 A. Designed for surface mount installation in SOP-8 packages, it functions within a temperature range of -40°C to +105°C. The IC includes built-in protections such as VCC under-voltage and overvoltage protection, along with SOURCE pin open protection.
Feature Summary
- Integrates a 650V耐压 switching MOSFET and start circuit to simplify design
- Employs PWM current mode control with per-cycle current limiting
- Supports both isolated and non-isolated AC/DC converter topologies
- Includes burst operation and frequency reduction for light load efficiency
Applications
- AC/DC power supplies for devices with power sockets
- Low-power isolated converter designs
- Non-isolated converter applications
Procurement Notes
Verify the specific suffix GE2 against official datasheets to confirm package type and compliance status. Confirm that the required output current of 1.3 A aligns with system demands, as other variants in the series offer different current ratings. Ensure compatibility with SOP-8 mounting requirements and check for any regional regulatory certifications relevant to the target market.
Selection Notes
Select this component when a fixed 65 kHz switching frequency and 1.3 A output capability are required. It is suitable for designs needing integrated high-voltage MOSFETs without external gate drivers. Consider alternative models like BM2P092F if higher output current or different packaging options are necessary. Verify thermal management needs for the SOP-8 package within the specified operating temperature range.
Part Context
This part belongs to the BM2PXX1F series of PWM DC/DC converters designed for AC/DC applications. The series emphasizes low power consumption and ease of design through integrated components. It targets consumer electronics and industrial equipment requiring compact, efficient power solutions with minimal external component count.
Replacement Considerations
BM2P092F-GE2 offers similar topology but with a 500mA output current rating. BM2P094F-GE2 provides comparable features with a 65 kHz frequency. Verify pinout compatibility and electrical parameters before substitution.
