| Description | The TPS54140DGQR is a high-performance step-down (buck) DC-DC switching regulator developed by Texas Instruments, designed for efficient power conversion in industrial and embedded systems. It integrates a high-side MOSFET, reducing external component count and simplifying design. This device operates over a wide input voltage range of 3.5V to 42V and delivers up to 1.5A output current, making it suitable for applications requiring stable and efficient voltage step-down conversion. The TPS54140DGQR utilizes current-mode control architecture, enabling simple compensation and fast transient response. It also features Eco-mode™ pulse-skipping operation, which significantly improves efficiency at light loads by reducing switching losses. The output voltage is adjustable from 0.8V up to approximately 39V, providing flexibility for various system requirements. It supports a programmable switching frequency from 100 kHz to 2.5 MHz, allowing optimization between efficiency and component size. Designed for low power consumption, the device features a typical quiescent current of around 116 µA and an ultra-low shutdown current of approximately 1.3 µA, making it ideal for energy-sensitive applications. The IC includes multiple protection features such as undervoltage lockout (UVLO), overvoltage protection, thermal shutdown, and adjustable soft-start, ensuring reliable and safe operation under varying conditions. Packaged in a compact 10-pin HVSSOP surface-mount package with PowerPAD™, the TPS54140DGQR provides excellent thermal performance and is suitable for high-density PCB designs. The TPS54140DGQR is widely used in industrial power supplies, automotive systems, communication equipment, distributed power architectures, and embedded electronics, where efficient, wide-input voltage regulation is required. |
