Overview
The BM2P0391-Z is a PWM type DC/DC converter IC manufactured by Rohm Semiconductor, designed for AC/DC conversion applications. It integrates a 650V MOSFET and operates within an input voltage range of 8.9V to 26V. The device utilizes a flyback topology with a fixed switching frequency of 100kHz and a maximum duty cycle of 82%. It features auto-restart functionality and consumes a typical operating supply current of 1mA. The component is housed in a 7-DIP package (DIP-7) suitable for through-hole mounting and supports operation across a temperature range of -40°C to +105°C.
Feature Summary
- Integrates a high-voltage 650V switching MOSFET to simplify circuit design
- Employs PWM current mode control for stable performance
- Includes built-in frequency hopping to reduce electromagnetic interference
- Features auto-restart protection for enhanced reliability
Applications
- Low power AC/DC converters for consumer electronics
- Standby power supplies for appliances with plug-in interfaces
- Non-isolated and isolated low-power converter designs
Procurement Notes
Verify the specific suffix designation to ensure compatibility with required packaging or environmental standards. Confirm that the DIP-7 through-hole package aligns with the target PCB layout constraints. Check RoHS compliance status against regional regulatory requirements before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring a compact solution with integrated high-voltage switching capabilities. The 100kHz switching frequency offers a balance between size and efficiency. Ensure the external current sense resistor values are calculated correctly to match the internal control thresholds for optimal transient response.
Part Context
This part belongs to the BM2P0391 series of AC/DC converters from Rohm Semiconductor. These devices are engineered for low-power systems, offering a cost-effective alternative to discrete solutions. The series supports both insulated and non-insulated topologies, making it versatile for various small appliance power supply designs.
Replacement Considerations
Direct substitutes include other parts within the BM2P0391 family, such as the BM2P0391. Verify pinout compatibility and electrical parameters like switching frequency and voltage ratings when considering cross-references.
