The TPS54425PWPRG4 from Texas Instruments is a highly efficient, synchronous step-down (buck) converter designed for various low-voltage applications. It features integrated FETs with low on-resistance (65 mΩ high side, 55 mΩ low side) for optimized efficiency, especially at lower duty cycles.
This converter supports a wide input voltage range of 4.5V to 18V and can deliver up to 4A of output current. The output voltage is adjustable from 0.76V to 5.5V. It utilizes the D-CAP2™ mode, which enables fast transient response, low output ripple, and allows the use of ceramic output capacitors.
The TPS54425PWPRG4 operates at a switching frequency of 700 kHz and includes features such as cycle-by-cycle over-current limit and power good output. The typical quiescent current is very low at 0.85 mA, with less than 10 µA at shutdown, contributing to power efficiency.
Packaged in an HTSSOP (PWP) with dimensions of 5 mm x 6.4 mm (32 mm²), this component is suitable for applications like digital TV power supplies, high-definition Blu-ray disc players, networking equipment, and digital set-top boxes. The operating temperature range is -40°C to 85°C.
