BM2P053F-G

Overview

The BM2P053F-G is a PWM type DC/DC converter IC from ROHM Semiconductor, designed for AC/DC conversion applications. It integrates a high-voltage startup circuit and a 650V MOSFET to facilitate low-power designs in both isolated and non-isolated topologies. The device operates with an input voltage range of 8.9 V to 26 V and supports a maximum output current of 2.6 A. It functions at a fixed switching frequency of 65 kHz and maintains operation within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a 650V耐压 high-voltage startup circuit and power MOSFET for simplified design
• Supports both isolated and non-isolated converter architectures
• Utilizes current mode control with per-cycle current limiting for stable performance

Applications

• Low-power electrical converters for products with power outlets
• Isolated AC/DC power supply designs
• Non-isolated AC/DC power supply designs

Procurement Notes

Verify the exact suffix against official documentation, as 'BM2P053F' variants may include specific packaging codes like '-GE2'. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors before procurement. Ensure the component grade meets application requirements, noting that standard grades may not be suitable for automotive use.

Selection Notes

Select this IC for applications requiring integrated high-voltage startup and MOSFET capabilities to reduce external component count. It is suitable for designs needing fixed 65 kHz switching frequencies and current mode control. Consider thermal management for SOP-8 packages operating up to 105°C. Verify compatibility with required isolation standards if used in isolated topologies.

Part Context

This component belongs to the BM2PXX3F series of PWM AC/DC converters by ROHM Semiconductor. The series focuses on achieving high efficiency and compact size through integrated power devices and protection circuits. These ICs are engineered to minimize light-load power consumption and incorporate noise reduction features for reliable operation in consumer and industrial power supplies.

Replacement Considerations

Check for direct pin-compatible alternatives within the same ROHM family, such as other BM2PXX3F variants with adjusted power ratings. Ensure any substitute maintains the 650V drain voltage rating and SOP-8 package dimensions. Verify that replacement parts support the same input voltage range and switching frequency specifications.
