TPS54302DDCT Buck Switching Regulator IC Positive Adjustable 0.596V 1 Output 3A
The TPS54302DDCT is a high-efficiency, 3A synchronous step-down (buck) converter from Texas Instruments, designed for compact power solutions in industrial, consumer, and automotive applications. Housed in an ultra-compact 6-pin SOT-23-THIN package, this chip integrates 85mΩ high-side and 40mΩ low-side MOSFETs to deliver up to 3A continuous output current from a wide 4.5V to 28V input voltage range. Operating at a fixed 400kHz switching frequency with internal loop compensation and 5ms soft-start, it achieves exceptional efficiency up to 95% while minimizing external component count. The device features advanced Eco-mode™ for light-load optimization and frequency spread spectrum for EMI reduction, making it ideal for space-constrained designs requiring robust power delivery and electromagnetic compatibility.
TPS54302DDCT Selection Advantages
The TPS54302DDCT offers compelling advantages for power supply designers seeking maximum integration in minimal space. Its SOT-23-6 package delivers 3A capability in a footprint 70% smaller than traditional SOIC-8 buck converters, enabling high-density designs for wearable and IoT applications. The integration of both high-side and low-side MOSFETs with boot recharge diode eliminates external power switches and diodes, reducing BOM to just input/output capacitors, an inductor, and feedback resistors.
