Overview
The BM2P249Q-Z is a non-isolated PWM DC/DC converter IC manufactured by ROHM Semiconductor, designed for AC/DC applications. It integrates a 650V MOSFET and operates within an input voltage range of 10.6 V to 26.8 V. The device features a fixed switching frequency of 100 kHz and supports current mode control with per-cycle current limiting. It includes built-in protections such as thermal shutdown, under-voltage lockout, and auto restart. The component is housed in a DIP-7 package and functions efficiently across temperatures from -40°C to +105°C.
Feature Summary
- Integrates a 650V super junction MOSFET and startup circuit for low power consumption
- Utilizes current mode control with per-cycle current limitation for superior transient response
- Incorporates frequency hopping function to reduce electromagnetic interference (EMI)
- Supports burst operation at light load to maintain high efficiency
Applications
- Non-isolated AC/DC converters for products with plugs
- Compact power supply designs utilizing built-in current detection resistors
- Systems requiring low standby power consumption
Procurement Notes
Verify the specific suffix 'Q' against official ROHM documentation to confirm package type and tape/reel specifications, as suffixes often denote packaging variations. Ensure compatibility with existing PCB footprints for the DIP-7 configuration. Cross-reference the datasheet for any updates on lead times or lifecycle status before finalizing procurement plans.
Selection Notes
Select this component for applications requiring a single-chip solution for non-isolated AC/DC conversion. The integrated 650V MOSFET simplifies design compared to discrete solutions. Consider the 100 kHz fixed switching frequency and EMI reduction features when designing for noise-sensitive environments. Verify that the input voltage range aligns with the system's power requirements.
Part Context
The BM2P249Q-Z belongs to ROHM's series of PWM DC/DC converter ICs with built-in switching MOSFETs. These components are engineered to provide efficient power systems for various plug-equipped devices. The series emphasizes compactness and energy efficiency through integrated circuits and advanced control methods like Nano Pulse Control technology principles.
Replacement Considerations
BM2P249TF-E2 shares similar electrical characteristics but differs in package type (SOP-8 vs DIP-7). BM2P134Q-Z offers comparable functionality with a 100 kHz switching frequency but may have different input voltage ranges. Verify pin compatibility and thermal performance when substituting.
