Description

TPS51486 – Dual-Output Synchronous Buck Regulator for Memory Power Rails

The TPS51486 is a high-efficiency, dual-output synchronous buck regulator designed to power DDR memory systems—specifically providing regulated output voltages for VDDQ and VTT rails. With programmable output voltages and integrated protection features, this device is ideal for applications requiring compact size, reliability, and tight voltage regulation.

It supports a wide input voltage range and high output current per channel, making it suitable for notebooks, desktops, embedded systems, and networking equipment.

Key Features & Benefits:

• Dual synchronous buck regulators for VDDQ and VTT

• Wide input voltage range (typically 4.5 V to 17 V)

• Supports up to 25 A per output channel

• Programmable output voltages using external resistors

• Integrated overcurrent and thermal protection

• Power Good (PG) signal output for system monitoring

• Remote voltage sensing for accurate regulation

• Compact QFN-18 package for space-constrained designs

Applications:

• DDR2, DDR3, DDR4 memory power subsystems

• Laptops, desktops, and servers
