TPS51116PWP Description

Short technical summary and product information.

The TPS51116PWP from Texas Instruments is a comprehensive power management IC designed for DDR, DDR2, DDR3, DDR3L, LPDDR3, and DDR4 memory systems. It integrates a synchronous buck controller and a 3A LDO (VTT) with a buffered reference (VREF).

The device boasts a wide input voltage range from 3.0V to 28V, making it suitable for various applications. The synchronous buck controller utilizes D-CAP mode for fast load transient response and supports ceramic output capacitors. It offers current sensing from Rds(on) or a resistor and includes protection features like Powergood, Overvoltage Protection, and Undervoltage Protection.

The 3A LDO is capable of sinking and sourcing current, with input available to optimize power losses. It requires minimal output capacitance and provides buffered, low-noise VREF output with accuracy within ±20 mV for both VREF and VTT. The TPS51116PWP supports soft-off in S4/S5 states and high-Z in S3.

Packaged in a 20-HTSSOP, the TPS51116PWP is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, with a typical quiescent current of 0.8 mA.
