TPS51716 datasheet

 

Description :

The TPS51716 provides a complete power supply for DDR2, DDR3, DDR3L, and LPDDR3 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 TPS51716 employs D-CAP2™ mode coupled with 500 kHz or 670 kHz operating frequencies that supports ceramic output capacitors without an external compensation circuit. The VTTREF tracks VDDQ/2 with excellent 0.8% accuracy. The VTT, which provides 2-A sink/source peak current capabilities, requires only 10-μF of ceramic capacitance. In addition, the device features a dedicated LDO supply input.

Features :

1. Synchronous Buck Controller (VDDQ)

2. Conversion Voltage Range: 3 to 28 V

3. Output Voltage Range: 0.7 to 1.8 V

4. 0.8% VREF Accuracy

5. D-CAP2 Mode for Ceramic Output Capacitors

6. Selectable 500-kHz/670-kHz Switching Frequencies

7. Optimized Efficiency at Light and Heavy Loads With Auto-Skip Function

8. Supports Soft-Off in S4/S5 States

9. OCL/OVP/UVP/UVLO Protections

10. Powergood Output
