Overview
The BM2P107QK-Z is a power factor correction (PFC) controller IC designed for high-efficiency AC-DC conversion applications. It integrates a PFC controller and a PWM controller within a single package to simplify design and reduce component count. The device supports continuous conduction mode (CCM) operation for the PFC stage, ensuring stable performance across varying load conditions. Key electrical parameters include an operating supply voltage range of 8.5V to 18V and a switching frequency adjustable via an external resistor. The IC features built-in protection mechanisms such as over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown to ensure reliable operation in demanding environments.
Feature Summary
- Integrated dual-controller architecture combining PFC and PWM functions
- Supports continuous conduction mode for enhanced efficiency
- Comprehensive protection features including OVP and thermal shutdown
Applications
- High-efficiency AC-DC power supplies
- Computer and server power units
- Telecommunications equipment power systems
Procurement Notes
Verify the exact ordering code suffix to confirm package type and tape/reel specifications. Ensure compatibility with the intended PCB footprint and soldering profile. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pin assignments before finalizing procurement.
Selection Notes
Select this component for designs requiring integrated PFC and PWM control to minimize bill of materials. Consider the thermal management requirements due to the integrated nature of the controllers. Verify that the input voltage range and output power requirements align with the IC's specified operational limits for optimal performance.
Part Context
This part belongs to Rohm Semiconductor's family of integrated power management solutions. It is designed to replace discrete PFC and PWM controller combinations, offering a compact solution for modern power supply designs. The BM2P107QK-Z is part of a series aimed at improving energy efficiency in consumer and industrial electronics.
Replacement Considerations
Direct substitutes may include other integrated PFC/PWM controllers from Rohm or competitors with similar pinouts and electrical characteristics. Verify functional compatibility and thermal performance when considering alternatives.
