The Texas Instruments TPS54425PWP is an active synchronous step-down (buck) converter designed for efficient power management. It features a wide input voltage range from 4.5V to 18V and can deliver up to 4A of output current.
The output voltage is adjustable, ranging from 0.76V to 5.5V, making it versatile for various low-voltage system applications. This device operates at a switching frequency of 700kHz, contributing to its compact solution size and fast transient response, especially with its D-CAP2™ control mode which allows for ceramic output capacitors.
Key electrical characteristics include a typical quiescent current of 0.00085A and a maximum duty cycle of 90%. The integrated FETs have a low on-resistance, with the high-side at 65mΩ and the low-side at 55mΩ, enhancing efficiency. The operating temperature range is -40°C to 85°C (TA).
Packaged in a 14-HTSSOP, the TPS54425PWP is suitable for surface mount applications. Its features include Enable, Power Good, and Soft Start, along with adjustable synchronous rectification. Applications include power supplies for digital TVs, high-definition Blu-ray players, networking equipment, and digital set-top boxes.
