Overview
The TPS54328DRCT, produced by Texas Instruments, is a 4.5-V to 18-V input, 3-A synchronous step-down converter. This device is part of the SWIFT™ converter family and is designed to provide a cost-effective, low-component-count solution for various end-equipment power bus regulators. The TPS54328 uses adaptive on-time D-CAP2™ mode control, which offers a fast transient response without the need for external compensation components. It supports seamless transition between PWM mode at higher load conditions and Eco-mode operation at light loads, ensuring high efficiency across a wide range of load conditions.
