The TPS62040DGQR from Texas Instruments is a highly efficient synchronous step-down DC/DC converter belonging to the esteemed family of power management integrated circuits. This product is specifically designed to cater to portable and space-constrained applications, providing a compact, reliable solution for power conversion.
With an input voltage range of 2.5V to 6.0V, the TPS62040DGQR is versatile and well-suited for operating from a single lithium-ion battery or other power supplies within its voltage range. It supports an adjustable output voltage from 0.7V to the maximum input voltage, allowing for a wide range of output configurations to match specific circuit requirements.
This converter boasts a high efficiency of up to 95%, which is achieved through its synchronous step-down regulator topology. The low on-resistance of its internal MOSFETs minimizes power loss and helps to extend battery life in portable devices. Moreover, the TPS62040DGQR operates at a fixed switching frequency of 1.2MHz, enabling the use of small surface-mount inductors and capacitors, which further contributes to a reduced footprint on the PCB.
The device comes in a compact 10-pin MSOP PowerPad package, designated by the DGQR suffix, providing excellent thermal performance in a small form factor. This package is particularly useful for thermal management in space-constrained applications.
Additional features of the TPS62040DGQR include over-temperature protection and over-current protection, which safeguard the device and the system it powers from adverse conditions. The device also has a Power Save Mode, which enhances efficiency at light loads, and a 100% duty cycle for low-dropout operation.
Texas Instruments’ commitment to quality and performance is evident in the TPS62040DGQR, making it an ideal choice for designers looking to implement an efficient power management solution in their next project. Whether it’s for handheld devices, wireless peripherals, or other portable electronics, this DC/DC converter is engineered to deliver reliable performance in a variety of applications.
