Mingjiada Electronics Supply: TI TPS51125ARGER——Dual-Synchronous Buck Controller

Shenzhen Mingjiada Electronics Co., Ltd.——Long-term supply of TI (TPS51125ARGER) 4.5V to 28V Dual Synchronous Buck Controller with 100mA LDO and flexible external components. This dual synchronous step-down controller is ideal for efficient power supply designs due to its excellent performance and wide application adaptability.

TPS51125ARGER Product Description 

The TPS51125ARGER is a highly flexible dual-channel synchronous buck controller chip. It is designed to drive external N-channel MOSFETs to build high efficiency, high performance buck converters. The device supports a wide input voltage range of 4.5V to 28V, making it easy to handle complex input environments such as multiple power adapters, battery packs, or industrial power buses. Each channel can independently output a stable voltage as low as 0.7V, meeting the low-voltage, high-current requirements of core circuits such as modern processors, ASICs, and FPGAs.

TPS51125ARGER Salient Product Features 

WIDE INPUT RANGE, HIGH ADAPTABILITY: A wide VIN of 4.5V to 28V is one of the core strengths of the TPS51125ARGER, making it compatible with a wide range of input sources.

High Efficiency Synchronous Rectification: The synchronous rectification architecture significantly reduces the conduction loss caused by traditional diode current renewal and improves the overall system efficiency, especially under medium to high loads.

Dual-channel independent control: The two channels work completely independently and can be configured for different output voltages and current capabilities, providing a compact solution for multi-voltage rail systems. Flexible configuration is an important value of the TPS51125ARGER.

High-precision Voltage Reference: Integrated high-precision voltage reference (±1% over-temperature) ensures the stability and accuracy of the output voltage.

Comprehensive Protection Functions: The TPS51125ARGER has built-in multiple protection mechanisms, including OVP, UVP, and OCP, to effectively enhance system reliability and safety.

Programmable Switching Frequency and Synchronisation: The switching frequency can be programmed through external resistors or synchronised with an external clock over a wide range, making it easy to optimise system efficiency and EMI performance.

Integrated Boot Diode: Integrated bootstrap diode simplifies external circuit design and reduces component count.

Small package: Compact 4mm x 4mm VQFN-24 (RGE) package saves valuable PCB space.

TPS51125ARGER Typical Application Types 

Thanks to its powerful features and flexibility, the TPS51125ARGER finds its use in a wide range of applications: 

Laptop/Ultrabook/Tablet: Provides multiple high-efficiency power supplies for CPU cores, GPUs, memories, chipsets, and more.

Network communication equipment: On-board multi-voltage rail power supply for routers, switches, gateways and other equipment.

Industrial and embedded systems: PLCs, industrial controllers, test and measurement instruments, and other applications requiring wide input range and reliability.

Servers and storage systems: Power supply for on-board ASICs, FPGAs, memory modules.

General Purpose Multiple DC/DC Power Systems: Any scenario that requires two highly efficient, adjustable low voltage outputs from a single wide input (e.g., 12V, 19V, 24V bus), the TPS51125ARGER is up to the task.
