Overview
The BM2P039-Z is a PWM type AC/DC converter IC from ROHM Semiconductor, designed for low-power power supply systems in products with plugs. It integrates a 650V MOSFET and a startup circuit to facilitate easy design of isolated and non-isolated converters. The device operates within a supply voltage range of 8.9 V to 26 V and features a fixed switching frequency of 100 kHz. It employs current mode control for excellent bandwidth and transient response, with auto restart capabilities and thermal shutdown protection.
Feature Summary
- Integrates a 650V耐压 MOSFET and startup circuit for simplified design
- Utilizes current mode control method for superior transient response
- Includes frequency hopping function to reduce electromagnetic interference
- Supports light load modes to enhance efficiency at low power
Applications
- Power supplies for consumer electronics with plug-in adapters
- Low-power AC/DC conversion systems
- Isolated and non-isolated converter designs
Procurement Notes
Verify the specific package variant (DIP7K) and RoHS compliance status before ordering. Confirm that the application does not involve automotive equipment, as this standard-grade product is explicitly not recommended for such use. Ensure the design accommodates the through-hole mounting style and DIP-7 footprint dimensions provided in the official datasheet.
Selection Notes
Select this component for applications requiring a fixed 100 kHz switching frequency and integrated high-voltage MOSFET. It is suitable for designs needing current mode control and EMI reduction via frequency hopping. Consider the operating temperature range of -40°C to +105°C and the 8.9 V to 26 V supply voltage window when defining system requirements.
Part Context
The BM2P039-Z belongs to the BM2P series of AC/DC converters from ROHM Semiconductor. This series focuses on achieving high efficiency and miniaturization by integrating POWER MOSFETs and rich protection circuits. The BM2P039-Z specifically targets low-power applications, offering a balance between performance and ease of design for standard-grade commercial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ROHM Semiconductor directly or review the BM2P series family for potential alternatives with similar specifications.
