TPS51200DRCR DDR memory power controller, voltage regulator Overview
The TPS51200DRCR is a high-performance, synchronous buck controller from Texas Instruments, specifically designed for DDR2, DDR3, DDR3L, and DDR4 memory power supply applications. This compact and efficient IC generates the VTT termination voltage (typically half of VDDQ) and VTTR reference voltage required for stable memory operation in servers, workstations, and high-speed computing systems. It supports an input voltage range of 2.5V to 5.5V, making it compatible with various power rail configurations, and delivers up to 3A of continuous output current with excellent load regulation.
A key feature of the TPS51200DRCR is its integrated MOSFET drivers, which reduce external component count and simplify PCB layout. The device employs adaptive on-time (AOT) control architecture, ensuring fast transient response to dynamic load changes in DDR memory systems. It includes automatic switching between PWM and low-power mode (LPM) to maximize efficiency across different load conditions. The IC also provides built-in power-good (PG) monitoring, soft-start functionality, and comprehensive protection features such as over-current protection (OCP), under-voltage lockout (UVLO), and thermal shutdown, enhancing system reliability.
The TPS51200DRCR comes in a 10-pin, 3mm × 3mm VSON (DRC) package, optimized for space-constrained designs. Its operating temperature range of -40°C to +85°C ensures robust performance in industrial and commercial environments. The device requires minimal external components, reducing BOM cost and board space. Additionally, it supports sink and source operation, which is critical for maintaining precise VTT voltage regulation during memory read/write cycles. This makes it an ideal solution for data center servers, networking equipment, and high-performance computing platforms where memory stability and power efficiency are paramount.
