Overview
The BM2P054F-GE2 is a PWM type DC/DC converter IC from ROHM Semiconductor, designed for AC/DC applications. It integrates a 650V MOSFET and a high-voltage start circuit 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 utilizes a fixed switching frequency of 70 kHz with a maximum duty cycle of 82%. The controller employs current mode control for superior bandwidth and transient response, featuring per-cycle current limiting. Operating temperatures range from -40°C to +105°C within an SOP-8 package.
Feature Summary
- Integrates a 650V耐压 MOSFET and start circuit for simplified design
- Supports both isolated and non-isolated power supply architectures
- Employs current mode control with per-cycle current limiting
- Includes protection mechanisms such as VCC under/overvoltage and SOURCE pin open protection
Applications
- Low-power AC/DC converters for devices with power sockets
- Isolated power supply designs
- Non-isolated power supply designs
- Compact electronic equipment requiring efficient power conversion
Procurement Notes
Verify the specific suffix GE2 against the official datasheet to confirm packaging and compliance status. Ensure the application environment remains within the specified -40°C to +105°C operating temperature range. Confirm that the external current detection resistor values align with the controller's requirements for accurate current limiting. Check for RoHS compliance documentation if required by the end-product regulations.
Selection Notes
Select this component when a combined controller and high-voltage switch are required to reduce board space. It is suitable for designs needing fixed frequency operation at 70 kHz. Consider the 2.6 A output capability and 82% max duty cycle for load requirements. The integrated start circuit eliminates the need for external biasing components during startup, simplifying the schematic.
Part Context
This part belongs to the BM2PXX4F series of PWM DC/DC converters optimized for AC/DC applications. The series is characterized by integrated FETs and features designed for low-power systems. It shares architectural similarities with other members like the BM2P094F but differs in specific electrical parameters and target output currents.
Replacement Considerations
Direct substitutes within the same family include parts with similar integration levels, though exact parameter matching is required. Verify compatibility with existing PCB footprints and thermal management solutions before substitution.
