The TPS62561DDC from Texas Instruments is a high-efficiency synchronous step-down converter optimized for portable applications. It provides an output current of up to 600 mA and supports an input voltage range of 2.5 V to 5.5 V, making it suitable for various battery-powered devices.
This converter operates at a fixed switching frequency of 2.25 MHz, entering a Power Save Mode at light load currents to maintain high efficiency across the entire load range. It features an output voltage accuracy of ±2.5% in PWM mode and a low quiescent current of 15 μA. The device also boasts 100% duty cycle capability for the lowest dropout voltage.
The TPS62561DDC is available in a compact TSOT-23-5 package, enabling small solution sizes. Its design allows for the use of small inductors and capacitors, further reducing the overall footprint. This makes it an ideal choice for space-constrained applications.
Applications include PDAs, Pocket PCs, Portable Media Players, and POL (Point-of-Load) applications. The device can be forced into fixed frequency PWM mode for low-noise applications by pulling the MODE pin high. In shutdown mode, current consumption is reduced to less than 1 μA.
