It packs into an 18-VFQFN package — small enough for dense point-of-load boards. ## Lifecycle and sourcing posture The TPS56C231RNNR carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or obsolescence risk for new designs. No drop-in replacement is listed on the official cross-reference; the closest functional peer from TI is the LMR33630APCQRNXRQ1, but that is a 3 A part in a different package (wettable-flank QFN), not a pin-compatible swap.","metaTitle":"TI TPS56C231RNNR Buck Regulator, 12A, 3.8-17V Input","metaDescription":"TI TPS56C231RNNR step-down buck regulator, 12A output, adjustable 0.6-5.5V, 400kHz/800kHz/1.2MHz, -40 to 125°C, 18-VQFN.
