It integrates a – Output Voltage Range: 0.7 V to 1.8 V synchronous buck regulator controller (VDDQ) with a – 0.8% VREF Accuracy 2-A sink/source tracking LDO (VTT) and buffered low – D-CAP™ Mode for Fast Transient Response noise reference (VTTREF). The TPS51216 employs D-CAP™ mode coupled with 300 kHz/400 kHz – Selectable 300 kHz/400 kHz Switching frequencies for ease-of-use and fast transient Frequencies response. The VTTREF tracks VDDQ/2 within – Optimized Efficiency at Light and Heavy excellent 0.8% accuracy. The VTT, which provides 2- Loads with Auto-skip Function A sink/source peak current capabilities, requires only 10-mF of ceramic capacitance. In addition, a – Supports Soft-Off in S4/S5 States dedicated LDO supply input is available. – OCL/OVP/UVP/UVLO Protections The TPS51216 provides rich useful functions as well – Powergood Output as excellent power supply performance. It supports • 2-A LDO(VTT), Buffered Reference(VTTREF) flexible power state control, placing VTT at high-Z in – 2-A (Peak) Sink and Source Current S3 and discharging VDDQ, VTT and VTTREF (soft- off) in S4/S5 state. Programmable OCL with low-side – Requires Only 10-m mF of Ceramic Output MOSFET RDS(on) sensing, OVP/UVP/UVLO and Capacitance thermal shutdown protections are also available. – Buffered, Low Noise, 10-mA VTTREF The TPS51216 is available in a 20-pin, 3 mm × 3 Output mm, QFN package and is specified for ambient – 0.8% VTTREF, 20-mV VTT Accuracy temperature from –40°C to 85°C. – Support High-Z in S3 and Soft-Off in S4/S5 • Thermal Shutdown • 20-Pin, 3 mm × 3 mm, QFN Package APPLICATIONS • DDR2/DDR3/DDR3L Memory Power Supplies • SSTL_18, SSTL_15, SSTL_135 and HSTL Termination 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 D-CAP is a trademark of Texas Instruments.
