The TPS62046DGQR from Texas Instruments is a 1.2A, high-efficiency step-down (buck) DC/DC switching regulator. It is designed to provide a fixed 3.3V output voltage from an input voltage range of 2.5V to 6.0V. This device operates at a switching frequency of 1.25MHz, contributing to its high efficiency of up to 95% and enabling the use of smaller external components.
Key features include a typical quiescent current of 18µA, making it suitable for power-sensitive applications. It supports power-save mode operation at light load currents and offers a 100% duty cycle for lowest dropout voltage. The regulator includes internal soft-start, dynamic output voltage positioning, thermal shutdown, and short-circuit protection for robust operation.
Packaged in a 10-pin MSOP or 10-HVSSOP, the TPS62046DGQR is designed for surface mount applications. Its compact size and performance characteristics make it suitable for various portable devices and power management solutions, including PDAs, smartphones, USB-powered modems, CPUs, DSPs, and PC cards.
