TPS53515 SWIFT™ Single-Channel Synchronous Buck Converter: 12A High-Current Server Power Solution | In Stock and Buyback
Product Overview
The TPS53515 is a high-performance 12A single-channel synchronous buck converter from Texas Instruments (TI) that utilizes the D-CAP3™ adaptive on-time control architecture. It is specifically designed for high-current, low-voltage applications such as servers and cloud computing point-of-load (POL) systems. The device integrates 13.8 mΩ and 5.9 mΩ power MOSFETs, supports input voltages from 1.5 V to 18 V (with VDD offset from 4.5 V to 25 V), and delivers up to 12 A of continuous output current, offering exceptional integration and efficiency advantages in server power supply designs.

Key Features and Technical Advantages
D-CAP3™ control mode, no loop compensation required
The TPS53515 employs TI’s proprietary D-CAP3 control mode, combined with an adaptive on-time architecture, to achieve ultra-fast load step response without the need for an external phase compensation network. This feature significantly simplifies the power supply design process, reduces the number of external components, and is particularly well-suited for space-constrained server motherboard designs.
Integrated Low-On-Resistance MOSFETs, 12A High-Current Output
The device integrates 13.8 mΩ (high-side) and 5.9 mΩ (low-side) power MOSFETs, supporting a continuous output current of 12 A. It meets the power requirements of high-current loads—such as server CPU cores, FPGAs, and DSPs—without the need for external power transistors. In typical server POL applications, this level of integration significantly reduces BOM area and design complexity.
Wide Input/Output Range for Flexible Adaptation to Various Power Supply Architectures
Input Voltage: 1.5 V to 18 V (VDD offset 4.5 V to 25 V)
Output Voltage: 0.6 V to 5.5 V, with a 600 mV reference voltage tolerance of only ±0.5%
Switching frequency: 8 selectable settings, ranging from 250 kHz to 1 MHz
Output capacitance: Supports all-ceramic capacitor solutions
The wide voltage range enables the TPS53515 to flexibly accommodate various intermediate bus voltages, such as 12 V and 5 V, covering a wide range of power supply scenarios including servers, network communications, and optical communications infrastructure.
High-Efficiency Light-Load Mode and Strict Output Accuracy
The TPS53515 supports Auto-skipping Eco-mode™, maintaining high conversion efficiency under light-load conditions; it also provides FCCM (Forced Continuous Conduction Mode) to meet the strict output voltage ripple requirements of DSPs and FPGAs. Additionally, the device features practical functions such as precharge startup, an integrated output discharge circuit, and an open-drain Power-Good output.
Compact Package
Housed in a 3.5 mm × 4.5 mm, 28-pin VQFN-CLIP package with an operating temperature range of –40°C to 85°C, it is suitable for high-density PCB layouts.
Application Scenarios: An Ideal Choice for Server Power Supply Design
Typical application areas for the TPS53515 include:
Servers and cloud computing point-of-load (POL): Providing core voltages and I/O power to CPUs, ASICs, and FPGAs on server motherboards
Broadband, networking, and fiber-optic communications infrastructure: Board-level power supplies for devices such as Ethernet switches, routers, and optical modules
I/O Power: Providing precise, low-voltage power to high-speed interface circuits
