BM2P014

Overview

The BM2P014 is a PWM type DC/DC converter IC designed for AC/DC applications, featuring an integrated 650V switching MOSFET. It supports both isolated and non-isolated topologies with a fixed switching frequency of 65kHz. The device operates within an input voltage range of 8.9V to 26V and delivers a maximum drain voltage of 650V. It utilizes current mode control for per-cycle current limiting and includes a built-in start circuit. The component is housed in a DIP-7 package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a 650V耐压 switching MOSFET and start circuit for simplified design
• Employs PWM current mode method with per-cycle current limiting
• Features frequency reduction and burst operation for high efficiency at light loads
• Includes built-in frequency hopping function to assist in achieving low EMI

Applications

• Low power AC/DC converters for consumer electronics
• Standby power supplies for devices with plugs or sockets
• Non-isolated and isolated DC/DC conversion systems

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the official ROHM Semiconductor datasheet prior to procurement. Confirm that the application environment remains within the specified operating temperature limits of -40°C to +105°C. Ensure that the design does not target automotive use, as this standard-grade product is explicitly noted as unsuitable for such equipment. Cross-reference the DIP-7 package dimensions with mechanical constraints.

Selection Notes

Select the BM2P014 when designing cost-effective AC/DC converters requiring an integrated power switch. The fixed 65kHz frequency and current mode control are suitable for applications prioritizing transient response and bandwidth. Consider the external current detection resistor requirement for flexible power design. This component is appropriate for general-purpose electronic devices rather than automotive or high-reliability industrial sectors.

Part Context

The BM2P014 belongs to the BM2PXX4 series of PWM type DC/DC converter ICs from ROHM Semiconductor. This series is engineered to provide efficient power systems for various products equipped with plugs. The family emphasizes low power consumption through features like frequency reduction and burst modes, while maintaining design simplicity via integrated high-voltage components.

Replacement Considerations

The BM2P034 is a confirmed substitute within the same series, sharing identical topology and package specifications but featuring a different MOSFET on-resistance value.
