Switching frequency is fixed at 100 kHz. ## Non-isolated buck — application boundary This is a non-isolated converter, meaning the output ground is the same node as the input return. The 75% maximum duty cycle sets the minimum input-to-output step-down ratio. ## Protection set and control interface The controller integrates current limiting, over-temperature shutdown, over-voltage protection, and under-voltage lockout. The enable pin (EN) and soft-start give the system designer control over sequencing and inrush. The VCC supply range of 10.6 V to 14.05 V means the IC needs an auxiliary bias rail — typically derived from a bootstrap winding or a small linear regulator off the bulk voltage. ## Package and board integration The supplier device package is 8-SOP. The 8-pin SOIC body is common and easy to route; the thermal pad is on the die attach paddle, so a via array under the package to the ground plane helps keep junction temperature in check at higher output currents. The part is ROHS3 compliant.","metaTitle":"ROHM BM2P137TKF-E2 PWM Buck Converter, 800V, 100kHz, 8-SOIC","metaDescription":"ROHM BM2P137TKF-E2 PWM DC/DC buck converter IC, 800V breakdown, 100kHz switching, 8-SOIC package.
