TPS51116 DDR Switcher & LDO

Texas Instruments TPS51116 DDR Switcher and LDO provides a complete power supply for DDR/SSTL-2, DDR2/SSTL-18, and DDR3 memory systems. This TI device integrates a synchronous buck controller with a 3A sink/source tracking linear regulator and buffered low noise reference. TPS51116 offers the lowest total solution cost in systems where space is at a premium. TPS51116 synchronous controller runs fixed 400kHz pseudo-constant frequency PWM with an adaptive on-time control that can be configured in D-CAP Mode for ease of use and fastest transient response or in current mode to support ceramic output capacitors. The 3A sink/source LDO maintains fast transient response only requiring 20µF (2×10µF) of ceramic output capacitance.
