BM2P034

Overview

The BM2P034 is a PWM type DC/DC converter IC featuring an integrated 650V MOSFET, designed for AC/DC applications with both isolated and non-isolated topologies. It operates within a supply voltage range of 8.9V to 26V and utilizes current mode control for per-cycle current limiting. The fixed switching frequency is 65kHz, which reduces during light load conditions to enhance efficiency. The device includes a built-in 650V start circuit and employs frequency hopping to minimize electromagnetic interference. It is housed in a DIP7 package and supports an operating temperature range from -40°C to 105°C.

Feature Summary

Integrates a 650V耐压 MOSFET and start circuit to simplify design and reduce low-power consumption.
Employs current mode control with per-cycle current limiting for superior bandwidth and transient response.
Features frequency reduction at light loads and built-in frequency hopping to achieve high efficiency and low EMI.

Applications

Low power AC/DC converters for consumer electronics
Isolated and non-isolated power supply designs
Adapters for devices with plug interfaces

Procurement Notes

Verify the specific suffix (e.g., Z) against the manufacturer's datasheet to confirm packaging and tape/reel specifications. Confirm RoHS compliance status as indicated in the official documentation. Ensure the application does not involve automotive equipment, as this standard-grade product is explicitly not recommended for such use. Cross-reference the DIP7 package dimensions with your PCB layout requirements.

Selection Notes

Select this component for designs requiring a simplified topology with an integrated high-voltage switch. It is suitable for applications needing fixed frequency operation at 65kHz with adaptive frequency reduction for efficiency. Consider its suitability for both isolated and non-isolated architectures. Evaluate the external current detection resistor requirement for flexibility in power design against the benefit of reduced component count.

Part Context

The BM2P034 belongs to the BM2PxX4 series of PWM DC/DC converter ICs by ROHM Semiconductor. This series targets low-power AC/DC conversion needs, offering integrated solutions that support various system insulation types. The family emphasizes ease of design through internal high-voltage circuits and efficient control methods, positioning it for general-purpose power adapter and charger applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official documentation or authorized distributors for verified cross-reference data before implementation.
