Overview
The BM2P015-Z is a PWM DC/DC converter IC designed for AC/DC applications in products with electrical outlets. It supports both isolated and non-isolated topologies to facilitate low-power converter designs. The device integrates a high-voltage startup circuit rated at 650V, which aids in achieving low power consumption. It employs current mode control with per-cycle current limiting for superior bandwidth and transient response. The switching frequency is fixed at 65 kHz, with frequency reduction features during light loads to enhance efficiency. Built-in frequency hopping helps reduce electromagnetic interference (EMI).
Feature Summary
- Integrates a 650V耐压 startup circuit and switching MOSFET for simplified design.
- Utilizes current mode control with per-cycle current limiting for stable performance.
- Features frequency reduction and burst operation modes to optimize light-load efficiency.
- Includes built-in frequency hopping functionality to mitigate electromagnetic interference.
Applications
- Power supplies for consumer electronics with electrical outlets
- Low-power AC/DC conversion systems
- Non-isolated DC/DC converter designs
Procurement Notes
Verify the specific package variant, as the BM2P015-Z series includes DIP7K configurations. Confirm RoHS compliance status through official documentation before integration. Ensure that the application does not involve automotive equipment, as this component is designated for standard-grade use only. Cross-reference the datasheet for exact thermal and electrical limits.
Selection Notes
Select this component for designs requiring integrated high-voltage startup and switching capabilities without external discrete MOSFETs. It is suitable for applications prioritizing low standby power and compact layouts due to internal current detection resistors. Consider the fixed 65 kHz frequency when designing magnetic components. Evaluate the need for isolation, as this part supports both isolated and non-isolated architectures depending on the external circuit configuration.
Part Context
This IC belongs to the BM2P series of PWM DC/DC converters from ROHM Semiconductor. The series is optimized for AC/DC converters used in devices with electrical sockets. These ICs are characterized by their ability to support both isolated and non-isolated topologies, simplifying the design process for various low-power conversion applications across different product categories.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official ROHM documentation or distributor databases for equivalent components within the BM2P family or other compatible PWM controller series.
