TPS59116 

A full suite of DDR, DDR2, and DDR3 memory power solutions, synchronous buck controllers for embedded computing

illustrate   The TPS59116 offers a DDR/SSTL-2, DDR2/SSTL-18 full power supply and DDR3 memory system. It integrates a three-A synchronous buck controller/source-traced linear regulator and buffered low-noise reference. The TPS59116 provides a system with the lowest cost of a total solution, where space is at a premium. The TPS59116 synchronous controller runs an adaptive fixed on-time control that can be configured for ease of use and the fastest transient response or current mode in D-D ™ mode to support PWM with a pseudo-fixed frequency of 400 kHz for ceramic output capacitors. 3. The receiver/source maintains a ceramic output capacitor of only 20μF (2×10μF) for the LDO with fast transient response.   characteristic   Synchronous Buck Controller (VDDQ available) Wide input voltage range: 3.0 V to 28-V ð - Mode 100™ - Load step response of ns The current mode option supports ceramic output capacitors S4/S5 countries that support soft shutdown R DS(on) or resistor detected from current 2.5-V (demobilization), 1.8-V (DDR2 memory), adjustable to 1.5-V (DDR3 memory) or output range 0.75-V to 3.0-V Equipped with a good power supply, overvoltage protection and undervoltage protection 3-A LDO (VTT), Buffer Reference (VREF) Capable receiver and a data three The LDO's input optimizes power loss A small 20μF ceramic output capacitor is required Buffered low-noise 10 mA VREF output Accuracy is ± 20 mV VREF and VTT Supports S3 with high Z and S4/S5 with soft shutdown Thermal shutdown apply DDR/DDR2/DDR3/LPDDR3 memory power supplies are supplied in embedded computing systems Surrey Satellite Technologies Ltd – 2 Surrey Satellite Technologies Ltd – 18 and HSTL terminated
