Rohm Semiconductor BM2PBB3YF-E2 Buck DC/DC Converter IC

The BM2PBB3YF-E2 is a high-performance non-isolated buck DC/DC converter IC from Rohm Semiconductor, designed for reliable power management in demanding applications. This surface-mount device features an internal switch with 730V breakdown voltage capability and operates across a wide supply voltage range of 11.1V to 26V. With integrated soft-start control and comprehensive fault protection including current limiting, over-temperature, and over-voltage safeguards, this converter ensures stable operation across the full -40°C to 105°C temperature range. The compact 8-SOIC package makes it ideal for space-constrained designs in automotive, industrial, and telecommunications applications.

Key Features:

  • Non-isolated buck topology with internal switching
  • 730V breakdown voltage for robust performance
  • 25kHz switching frequency
  • Wide operating voltage: 11.1V ~ 26V
  • Comprehensive protection: current limiting, over-temperature, over-voltage
  • Soft start control for reduced inrush current
  • Extended temperature range: -40°C to 105°C
  • RoHS compliant
