TPS51633

TPS51633 SLUSEW4 – JUNE 2022 TPS51633 3-Phase, D-CAP+™ Step-Down Controller for VR12.6 VCPU 1 Features Intel® VR12.6 PWM Specification serial VID (SVID) compliant 1-, 2-, or 3-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 800-kHz 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 2 Applications Adapter Battery NVDC 5-V or 12-V Rails 3 Description The TPS51633 device is a driverless step-down controller that is fully compliant with the SVID communications protocol, meeting the Intel VR12.6 specification. Advanced control features such as DCAP+ architecture with overlapping pulse support undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency. The TPS51633 device also supports single-phase operation in CCM or DCM for light-load efficiency. The TPS51633 device integrates the full complement of VR12.6 I/O featu...
