Overview
The BM2P031 is a PWM type DC/DC converter IC designed for AC/DC conversion, featuring an integrated 650V MOSFET and start circuit. It operates with a fixed switching frequency of 65kHz and supports an input voltage range from 8.9V to 26V. The device delivers a maximum output current of 775mA and utilizes current mode control for per-cycle current limiting. It is housed in a 7-DIP package and functions within a temperature range of -40°C to 105°C.
Feature Summary
- Integrates a 650V耐压 MOSFET and start circuit to simplify design and reduce low-load power consumption.
- Employs current mode control with per-cycle current limiting to ensure excellent bandwidth and transient response.
- Features burst operation and frequency reduction during light loads to achieve high efficiency.
- Includes built-in frequency hopping functionality to assist in achieving low electromagnetic interference.
Applications
- Low-power AC/DC converters for consumer electronics
- Insulated and non-insulated power supply designs
- Standby power systems for devices with plugs
Procurement Notes
Verify the specific package variant, such as DIP7 or DIP7K, against the required board layout before ordering. Confirm that the application does not involve automotive equipment, as this component is explicitly not recommended for such use. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product assembly.
Selection Notes
Select this component for designs requiring a simplified topology with an integrated high-voltage switch. It is suitable for applications needing fixed frequency operation at 65kHz and efficient light-load performance through burst modes. Consider the external current detection resistor requirement for flexible power design adjustments.
Part Context
The BM2P031 belongs to the BM2PXX1 series of AC/DC PWM converters by Rohm Semiconductor. This series targets low-power systems, offering solutions for both insulated and non-insulated topologies. The component is classified as a standard-grade product intended for general-purpose electronic devices rather than specialized industrial or automotive sectors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official manufacturer resources for potential cross-references or updated series replacements.
