The TPS54328 from Texas Instruments is a synchronous buck converter designed for a wide range of low-voltage applications. It operates with an input voltage range of 4.5 V to 18 V and can deliver an output current of up to 3 A, with an adjustable output voltage from 0.76 V to 7 V.
This converter features D-CAP2 mode control, which enables fast transient response without requiring external compensation components. It seamlessly transitions between PWM mode at higher loads and Eco-mode at light loads, maintaining high efficiency. The integrated FETs have a low on-resistance (100 mΩ high-side, 70 mΩ low-side) and are optimized for lower duty cycle applications.
The TPS54328 operates at a switching frequency of 700 kHz and includes cycle-by-cycle overcurrent limit protection. It supports adjustable soft start and pre-biased soft start functionality. The device is available in 8-pin DDA and 10-pin DRC packages, designed for surface mount installation, and operates within an ambient temperature range of -40°C to 85°C.
Key features include low output ripple, compatibility with ceramic output capacitors, and high efficiency with very low shutdown current (less than 10 µA). Applications include digital TV power supplies, high-definition Blu-ray disc players, networking home terminals, and digital set-top boxes.
