SLUS609H – MAY 2004 – REVISED JULY 2009 COMPLETE DDR, DDR2 AND DDR3 MEMORY POWER SOLUTION SYNCHRONOUS BUCK CONTROLLER, 3-A LDO, BUFFERED REFERENCE 2 • Synchronous Buck Controller (VDDQ) – Wide-Input Voltage Range: 3.0-V to 28-V The TPS51116 provides a complete power supply for DDR/SSTL-2, DDR2/SSTL-18, and DDR3 memory – D −CAP™ Mode with 100-ns Load Step systems. It integrates a synchronous buck controller Response with a 3-A sink/source tracking linear regulator and – Current Mode Option Supports Ceramic buffered low noise reference. The TPS51116 offers Output Capacitors the lowest total solution cost in systems where space is at a premium. The TPS51116 synchronous – Supports Soft-Off in S4/S5 States controller runs fixed 400kHz pseudo-constant – Current Sensing from RDS(on) or Resistor frequency PWM with an adaptive on-time control that – 2.5-V (DDR), 1.8-V (DDR2), Adjustable to can be configured in D-CAP™ Mode for ease of use 1.5-V (DDR3) or Output Range 0.75-V to and fastest transient response or in current mode to 3.0-V support ceramic output capacitors. The 3-A sink/source LDO maintains fast transient response – Equipped with Powergood, Overvoltage only requiring 20- µF (2 × 10 µF) of ceramic output Protection and Undervoltage Protection capacitance. In addition, the LDO supply input is • 3-A LDO (VTT), Buffered Reference (VREF) available externally to significantly reduce the total – Capable to Sink and Source 3 A power losses. The TPS51116 supports all of the sleep state controls placing VTT at high-Z in S3 – LDO Input Available to Optimize Power (suspend to RAM) and discharging VDDQ, VTT and Losses VTTREF (soft-off) in S4/S5 (suspend to disk). – Requires only 20- µF Ceramic Output TPS51116 has all of the protection features including Capacitor thermal shutdown and is offered in both a 20-pin HTSSOP PowerPAD™ package and 24-pin 4 ״ QFN. – Buffered Low Noise 10-mA VREF Output – Accuracy 20 mV for both VREF and VTT – Supports High-Z in S3 and Soft-Off in S4/S5 • DDR/DDR2/DDR3/LPDDR3 Memory Power – Thermal Shutdown Supplies • SSTL-2 SSTL-18 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, PowerPAD are trademarks of Texas Instruments.
