TPS51216MRUKREP

TEXAS INSTRUMENTS  TPS51216MRUKREP  芯片, 稳压器, LDO, 0.7V-1.8V, 2A, WQFN-20 新

The TPS51216-EP provides a complete power supply for DDR2, DDR3 and DDR3L memory systems in the lowest total cost and minimum space. It integrates a synchronous buck regulator controller VDDQ with a 2-A sink/source tracking LDO VTT and buffered low noise reference VTTREF. The TPS51216-EP employs D-CAP mode coupled with 300 kHz/400 kHz frequencies for ease-of-use and fast transient response. The VTTREF tracks VDDQ/2 within excellent 0.8% accuracy. The VTT, which provides 2-A sink/source peak current capabilities, requires only 10-µF of ceramic capacitance. In addition, a dedicated LDO supply input is available.

The TPS51216-EP provides rich useful functions as well as excellent power supply performance. It supports flexible power state control, placing VTT at high-Z in S3 and discharging VDDQ, VTT, and VTTREF soft-off in S4/S5 state.

Programmable OCL with low-side MOSFET RDSon sensing, OVP/UVP/UVLO and thermal shutdown protections are also available.

The TPS51216-EP is available in a 20-pin, 3 mm × 3 mm, WQFN package and is specified for junction temperature from -55°C to 125°C.
