BM2P091

Overview

The BM2P091 is a PWM type DC/DC converter IC designed for AC/DC applications. It integrates a 650V MOSFET and a start circuit, supporting input voltages from 8.9V to 26V with a maximum drain voltage of 650V. The device operates at a fixed switching frequency of 65kHz using current mode control. It features an on-resistance of 8.5Ω for the integrated FET. The component functions within an operating temperature range of -40°C to 105°C and is housed in a DIP7 package measuring 9.27x6.35mm.

Feature Summary

Integrates a 650V耐压 MOSFET and start circuit for simplified design
Utilizes current mode control with per-cycle current limiting for superior transient response
Incorporates frequency reduction and burst operation modes to enhance efficiency under light loads
Includes built-in frequency hopping functionality to assist in achieving low EMI performance

Applications

AC/DC converters for devices with power sockets
Insulated power supply designs
Non-insulated power supply designs
Low-power converter systems

Procurement Notes

Verify the specific suffix and packaging configuration against the official datasheet before ordering. Confirm that the application does not require automotive qualification, as this standard-grade product is explicitly not recommended for车载 equipment. Ensure the DIP7 package dimensions align with the target PCB layout requirements.

Selection Notes

Select this component for designs requiring a fixed 65kHz switching frequency and integrated high-voltage switching capability. It is suitable for applications needing current mode control for stable regulation. Consider the 8.5Ω on-resistance for thermal management calculations. This part is intended for general-purpose AC/DC conversion rather than specialized automotive or industrial environments requiring higher grades.

Part Context

The BM2P091 belongs to the BM2PXX1 series of PWM DC/DC converter ICs from Rohm Semiconductor. This series is optimized for AC/DC conversion in consumer electronics and appliances featuring power plugs. The family focuses on providing efficient, low-power solutions through integrated MOSFETs and advanced control methods like frequency hopping and burst mode operation.
