BM2P107QKF-E2

Overview

The BM2P107QKF-E2 is a non-insulated PWM DC/DC converter IC with an integrated switch MOSFET. It features an 800V breakdown voltage super junction MOSFET and an integrated start circuit, enabling low-power design for devices with plugs. The controller uses current mode control with per-cycle current limiting for excellent bandwidth and transient response. The oscillation frequency is fixed at 100kHz, and it includes a frequency hopping function to reduce EMI. Key electrical parameters include a minimum input voltage of 8V, maximum input voltage of 10.81V, drain max voltage of 800V, on-resistance of 7.5Ω, and an operating temperature range from -40°C to 105°C.

Feature Summary

• Integrates an 800V耐压 super junction MOSFET and start circuit for simplified high-voltage design.
• Employs current mode control with per-cycle current limiting to ensure stable performance.
• Includes a built-in frequency hopping function to assist in achieving low electromagnetic interference.
• Supports burst operation at light load conditions to enhance efficiency during low power states.

Applications

• Non-insulated high-efficiency converters for consumer electronics
• Power supplies for products with plug interfaces
• General purpose AC/DC conversion systems

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure that the application does not involve automotive equipment, as this product is explicitly stated as unsuitable for such use. Cross-reference the SOP-8 package dimensions and thermal characteristics with your PCB layout requirements before finalizing the procurement order.

Selection Notes

Select this component when designing non-insulated DC/DC converters requiring an integrated high-voltage switch. It is suitable for applications needing fixed 100kHz switching frequency and low EMI through frequency hopping. Consider its suitability for standard-grade industrial or consumer applications rather than automotive environments due to explicit usage restrictions.

Part Context

This part belongs to ROHM Semiconductor's line of integrated power management ICs designed for AC/DC conversion. It combines the controller and power switch into a single package to reduce external component count. The BM2P series typically targets cost-effective and compact power supply designs for general electronic devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pinout, electrical ratings, and thermal performance with alternative non-insulated PWM controllers from the same manufacturer family.
