| Description | The TPS57040QDGQRQ1 is a highly efficient step-down (buck) DC/DC switching regulator developed by Texas Instruments, specifically designed for automotive and industrial power management applications. It integrates a high-side MOSFET and utilizes current-mode control to provide stable and flexible voltage regulation. This device supports a wide input voltage range of 3.5V to 42V and delivers up to 0.5A output current, making it suitable for converting high input voltages to regulated low-voltage rails in embedded systems. The output voltage is adjustable from approximately 0.8V up to 39V, enabling versatile design configurations. The TPS57040QDGQRQ1 operates with a configurable switching frequency ranging from 100 kHz to 2.5 MHz, allowing designers to optimize efficiency and external component size. It also supports synchronization to an external clock for improved system integration. Featuring advanced Eco-mode™ pulse-skipping operation, the device achieves high efficiency at light loads while maintaining a low quiescent current of approximately 116 µA, making it suitable for power-sensitive applications. The device includes a range of integrated protection and control features such as adjustable soft-start, undervoltage lockout (UVLO), power-good output, thermal shutdown, and frequency foldback, ensuring reliable operation under varying conditions. Qualified to AEC-Q100 automotive standards, the TPS57040QDGQRQ1 operates over a temperature range of -40°C to +125°C, making it ideal for harsh environments and automotive-grade systems. Packaged in a compact 10-pin HVSSOP PowerPAD surface-mount package, the device provides excellent thermal performance and is well-suited for space-constrained PCB layouts. The TPS57040QDGQRQ1 is widely used in automotive electronics, industrial control systems, distributed power systems, battery-powered equipment, and embedded power supply designs, where efficient and robust voltage conversion is required. |
