TPS51624

TPS51624 SLUSEW5 – JUNE 2022 2-Phase, D-CAP+™ Step-Down Controller for VR12.6 VCPU 1 Features 3 Description Intel® VR12.6 PWM Specification serial VID (SVID) compliant 1- or 2-phase operation Full VR12.6 mobile feature set including digital current monitor, PS3 and PS4 operation 8-Bit DAC with 0.50-V to 2.30-V output range 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 1.5-MHz frequency selections Patented AutoBalance phase balancing Selectable 8-level current limit 4.5-V to 28-V conversion voltage range Small, 4 × 4, 32-pin, QFN PowerPAD™ integrated circuit package The TPS51624 is a driverless, fully SVID compliant, VR12.6 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 TPS51624 also supports single-phase operation in CCM or DCM for lightload efficiency. The TPS51624 integrates the full complement of VR12.6 I/O features including VR_READY (PGOOD), ALERT and VR_HOT. The SVID interface address allows programming from 0 to 7. In PS4, the quiescent power consumption of controller is t...
