BM2P241W-Z

Overview

The BM2P241W-Z is a non-isolated PWM DC-DC converter IC designed for AC-DC applications, featuring an integrated 650V super junction switching MOSFET. It operates within a supply voltage range of 12 V to 26.78 V and utilizes a fixed 65 kHz switching frequency. The device employs current mode control with per-cycle current limiting and includes a built-in startup circuit to reduce power consumption. Key protection features include thermal shutdown, under-voltage lockout, and auto-restart capabilities.

Feature Summary

Integrates a 650V super junction MOSFET and startup circuit for simplified design
Utilizes current mode control for superior bandwidth and transient response
Incorporates frequency hopping technology to minimize electromagnetic interference
Supports burst operation at light loads to enhance efficiency

Applications

Non-isolated AC-DC converters for products using wall adapters
Low-power system power supplies requiring high efficiency
Compact power designs utilizing built-in current detection resistors

Procurement Notes

Verify the specific suffix 'W' indicates the DIP-7 package configuration. Confirm RoHS compliance status through official documentation. Ensure the application environment remains within the specified -40°C to +105°C operating temperature range. Validate that the input voltage does not exceed the maximum drain voltage rating of 650V during transient conditions.

Selection Notes

Select this component for non-isolated topologies requiring integrated switching elements. Consider the fixed 65 kHz frequency for EMI management strategies. Evaluate the need for burst mode operation based on light load efficiency requirements. Ensure the design accommodates the through-hole DIP-7 package dimensions and thermal characteristics.

Part Context

This part belongs to ROHM's standard-grade AC-DC converter series. It is distinct from automotive-grade variants and is explicitly not recommended for use in vehicle-mounted equipment. The device represents a solution for reducing system size and cost through high integration of control logic and power stages.
