Texas Instruments TPS51216 DDR2, DDR3 and DDR3L Memory Power Solution Synchronous Buck Controller, 2-A LDO, Buffered Reference FX004Z

The TPS51216 is a synchronous buck controller designed for DDR2, DDR3, and DDR3L memory power solutions. It operates with a conversion voltage range of 3V to 28V and supports output voltages from 0.7V to 1.8V, achieving an accuracy of 0.8% for the reference voltage. The device features D-CAP,Ñ¢ mode for fast transient response and offers selectable switching frequencies of 300 kHz or 400 kHz, optimizing efficiency for both light and heavy loads through an auto-skip function. This product integrates a 2-A low-dropout regulator (LDO) for VTT, which provides peak sink/source current capabilities and requires only 10 OºF of ceramic capacitance. The TPS51216 includes essential protection features such as overcurrent limit (OCL), overvoltage protection (OVP), undervoltage protection (UVP), and undervoltage lockout (UVLO). It also supports soft-off functionality in low power states (S4/S5) and has a power-good output indicator. The device is housed in a compact 20-pin, 3 mm x 3 mm QFN package and is rated for operation in ambient temperatures ranging from -40¬8C to 85¬8C. This makes the TPS51216 suitable for applications requiring reliable memory power supplies in various environments.
