Dual-channel, 16-phase step-down, digital multiphase D-CAP++ controller with SVID, SVI3 and PMBus

The TPS537x2 family of step-down controllers are high-performance, dual output multiphase controllers available in 8-phase, 12-phase, and 16-phase package options. The controller has a high degree of programmability with support for up to eight separate pin-selectable configurations. Advanced control features such as Dual-edge D-CAP+™ (DDCAP+) architecture with native TLVR support and full PID loop provide fast transient response and good current sharing minimizes output capacitance requirements and saves system cost. Controllers are fully compatible with relevant TI smart power stages. The device also provides a novel phase interleaving strategy and optional phase shedding for efficiency improvements at different loads and long term reliability improvements. All programmable parameters can be reported and configured by the PMBus interface and can be stored in NVM as the new default values to minimize the external component count.
