The TPS54140QDGQRQ1 from Texas Instruments is a 1.5A, 42V step-down (buck) DC/DC converter featuring an integrated high-side MOSFET. This device utilizes current-mode control for simplified external compensation and flexible component selection.
Key electrical specifications include a wide 3.5V to 42V input voltage range, a maximum output current of 1.5A, and a typical operating quiescent current of 116µA, reducing to 1.3µA in shutdown mode. The switching frequency can be adjusted from 100kHz to 2.5MHz, allowing for optimization of efficiency and component size. It also features a 0.8V internal voltage reference and a maximum duty cycle of 98%.
This converter is designed for applications such as 12V and 24V industrial power systems and aftermarket automotive accessories. It supports adjustable undervoltage lockout (UVLO) and hysteresis, adjustable slow start/sequencing, and provides an undervoltage and overvoltage power-good output signal. The device operates within a temperature range of -40°C to 125°C.
The TPS54140QDGQRQ1 is available in a 10-pin HVSSOP (DGQ) package and a 10-pin VSON (DRC) package, both supporting surface mount.
