The TLV62130RGT is a synchronous step-down DC-DC converter IC from Texas Instruments, designed for high-power density laptop and MacBook logic board power sections. It supports input voltages from 3 V to 17 V and provides up to 3 A continuous output current. With fast transient response and high efficiency using DCS-Control™ topology, this IC ensures stable voltage regulation for CPU, GPU, and system rails. Markings commonly found on the IC top include VBUI or VUNI, depending on the batch.
