The controller integrates the D-CAP+™ modulation for fast transient response without external compensation — the loop stability is set by the output filter components, not by an external RC network.","metaTitle":"TI TPS53661RSBT VR12.5 Controller, 4.5-20V Input, 40-WQFN","metaDescription":"Active-production Intel VR12/VR12.5 single-output controller.
