TPS53625RSMT

TPS53625 SLUSEW7 – JUNE 2022 TPS53625 2-Phase, D-CAP+™ Step-Down Controller for VR12.0 VCPU 1 Features 3 Description • • • The TPS53625 device is a driverless, fully SVID compliant, VR12.0 step-down controller. Advanced control features such as D-CAP+ architecture with overlapping pulse support undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency. The TPS53625 device also supports single-phase operation in CCM or DCM for lightload efficiency. The TPS53625 device integrates the full complement of VR12.0 I/O features including VR_READY (PGOOD), ALERT and VR_HOT. The SVID interface address allows programming from 0 to 7. Adjustable control of VOUT slew rate and voltage positioning round out the VR12.0 features. • • • • • • • • • • • VR12.0 serial VID (SVID) compliant 1- or 2-phase operation Supports both zero-load and non-zero-load line applications 8-Bit DAC output range: 0.25 V to 1.52 V Optimized efficiency at light and heavy loads 8 independent levels of overshoot reduction (OSR) and undershoot reduction (USR) Driverless configuration for efficient high-frequency switching Supports discrete, Power Block, Power Stage or DrMOS MOSFET implementations Accurate, adjustable voltage positioning 300-kHz to 1-MHz frequency selections Patented AutoBalance Phase Balancing Selectable 8-level current limit 4.5-V to 28-V conversion voltage range Small, 4 mm × 4 mm, 32-Pin, VQFN PowerPAD™ integrated circuit package 2 Applications • Core Memory Paired with the TPS51604 FET gate driver, the solution delivers exceptionally high speed and low switching loss. The TPS53625 device works with selected TI power stage products for optimum efficiency as well as DrMOS products. The TPS53625 device operates with a default boot voltage of 1 V. Applications can override the default boot voltage by including an external resistor divider in the design. The TPS53625 device package is a space saving, thermally enhanced 32-pin VQFN package that operates from –40°C to 105°C.

All trademarks are the property of their respective owners. 5.4 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 5.5 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 6 Mechanical, Packaging, and Orderable Information The following pages include mechanical packaging and orderable information.
