Overview
The BM2P051F-GE2 is a PWM type DC/DC converter IC manufactured by ROHM Semiconductor, designed for AC/DC conversion applications. It integrates a 650V switching MOSFET and a high-voltage start circuit to facilitate low-power designs in both isolated and non-isolated topologies. The device operates with a fixed switching frequency of 65 kHz and utilizes current mode control for precise regulation. Key electrical parameters include an input voltage range of 8.9 V to 26 V, a maximum drain voltage of 650 V, and an on-resistance of 4 Ω for the integrated MOSFET. It supports operation across a temperature range of -40°C to +105°C.
Feature Summary
- Integrates a 650V withstand voltage start circuit and switching MOSFET to simplify power supply design.
- Employs current mode control with per-cycle current limiting to ensure stable bandwidth and transient response.
- Features burst operation during light loads and frequency reduction functions to enhance efficiency and reduce EMI.
Applications
- Low-power AC/DC converters for devices with power sockets
- Isolated and non-isolated power supply designs
- Consumer electronics requiring compact AC/DC conversion
Procurement Notes
Verify the complete part number including the suffix GE2 to ensure correct packaging and tape configuration. Confirm RoHS compliance status as specified in the official datasheet. Check for any specific handling requirements related to the SOP-8 package. Ensure compatibility with the intended thermal management solution given the operating temperature range. Validate that the application does not require automotive-grade certification, as this product is not recommended for vehicle equipment.
Selection Notes
Select the BM2P051F-GE2 for applications requiring a simplified design with an integrated high-voltage MOSFET. It is suitable for systems needing a fixed 65 kHz switching frequency and current mode control. Consider this component when designing for low standby power consumption using burst mode capabilities. Ensure the external current detection resistor matches the desired output specifications. Verify that the 8.9 V to 26 V input range aligns with the system's Vcc supply requirements.
Part Context
This component belongs to the BM2PXX1F series of PWM type DC/DC converter ICs from ROHM Semiconductor. The series is optimized for AC/DC converters, offering integrated solutions that reduce component count. The BM2P051F-GE2 variant specifically provides a standard-level performance profile within this family, focusing on ease of design for various low-power converter forms.
Replacement Considerations
