TPS62261TDRVRQ1

The TPS62261TDRVRQ1 from Texas Instruments is a high-efficiency synchronous step-down DC-DC converter designed for battery-powered applications. It is qualified for automotive applications and supports an input voltage range from 2V to 6V, making it suitable for Li-Ion batteries with extended voltage ranges, two or three cell alkaline batteries, and 3.3V or 5V input rails.

This converter operates at a fixed 2.25MHz switching frequency and can deliver an output current of up to 600mA. It features a fixed output voltage of 1.8V with an accuracy of ±1.5% in PWM mode. The device enters Power Save Mode at light load currents to maintain high efficiency across the entire load current range, optimized for low output voltage ripple. It also boasts a low quiescent current of 15µA (typical).

The TPS62261TDRVRQ1 is available in a compact 6-WSON package measuring 2x2x0.8mm, allowing for low-profile solutions with a height of less than 1mm. This makes it ideal for space-constrained applications such as PDAs, pocket PCs, low power DSP supplies, portable media players, and other POL applications.

Key electrical specifications include an input voltage range of 2V to 6V, an output current capability of 600mA, and a fixed switching frequency of 2.25MHz. The device operates within an ambient temperature range of -40°C to 105°C. It is supplied in a 6-pin WSON package and is available on tape and reel.
