Each phase shares the current, reducing ripple and spreading thermal load. The switching frequency is programmable from 300 kHz to 1 MHz, letting you trade inductor size against efficiency. The I²C bus provides digital control of the output voltage and fault monitoring — a step up from analog-only controllers. ## Active lifecycle — no end-of-life risk It is ROHS3 compliant. For new designs or BOM refreshes, this part is available through independent distribution and is sourced to order against an RFQ — no last-time-buy window to track. ## Package and footprint notes The 32-VQFN (4x4 mm) with exposed pad requires a thermal via array under the pad for adequate heat transfer to the PCB ground plane. Surface-mount assembly is standard; the exposed pad is the primary thermal path.","metaTitle":"TPS53632RSMT D-CAP+™ Buck Controller, 3-Phase PWM, I²C","metaDescription":"TI TPS53632RSMT 3-phase step-down buck controller with I²C interface, 300kHz-1MHz switching, 2.5V-24V supply, 32-VQFN.
