BM2P134QF-E2

Overview

The BM2P134QF-E2 is a non-isolated PWM DC/DC converter IC from ROHM Semiconductor, designed for high-efficiency AC/DC power supplies in products with AC plugs. It integrates a 650V super junction MOSFET and a startup circuit to facilitate low-power designs. The device operates within an input voltage range of 10.6 V to 14.05 V and features a fixed switching frequency of 100 kHz. Packaged in SOP-8, it supports an operating temperature range from -40°C to +105°C.

Feature Summary

Integrates a 650V super junction MOSFET and a high-voltage startup circuit for simplified design and low standby power consumption.
Employs current mode control with per-cycle current limiting to ensure stable bandwidth and transient response performance.
Includes built-in frequency hopping and burst operation modes at light loads to minimize electromagnetic interference (EMI) and improve efficiency.

Applications

Non-isolated AC/DC power supply systems
Power adapters for consumer electronics
Standby power circuits for devices with AC plugs

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's latest datasheet to confirm compliance with RoHS directives and packaging specifications. Ensure the SOP-8 package dimensions match your PCB footprint requirements. Confirm that the application does not require automotive-grade qualification, as this series is designated for standard industrial use only.

Selection Notes

Select this component for non-isolated applications requiring integrated high-voltage switching capabilities. It is suitable where fixed 100 kHz operation aligns with EMI constraints. Consider alternative models if isolated topology or different input voltage ranges are required. Verify thermal management needs given the SOP-8 package size and maximum operating temperature rating.

Part Context

This part belongs to the BM2P1xxQF series of PWM DC/DC converters. These ICs are engineered for compact, efficient power solutions in AC-powered equipment. The series emphasizes integration by combining control logic with robust power switches, reducing external component count and board space while maintaining reliable performance across varying load conditions.
