TPS54202DDCR - 2A Synchronous Buck Switching Regulator IC, 4.5V–28V Input, SOT-23-6 Package

The TPS54202DDCR from Texas Instruments is a high-efficiency 2A synchronous buck converter designed to deliver reliable power conversion in compact spaces. Operating over a wide input voltage range of 4.5V to 28V, this device integrates both the high-side and low-side MOSFETs (148mΩ and 78mΩ respectively), achieving high power density and excellent thermal performance in a space-saving SOT-23-6 package. It features internal loop compensation, 5 ms soft-start, and Eco-mode operation for superior light-load efficiency. The fixed 500 kHz switching frequency and frequency spread spectrum minimize EMI emissions, ensuring compliance with stringent electromagnetic standards. Protection features such as cycle-by-cycle current limiting, hiccup mode, overvoltage protection, and thermal shutdown enhance device safety and system reliability. This regulator is ideal for industrial, consumer, and communication systems, providing a compact, efficient, and robust DC-DC conversion solution.

Key Features:

Wide Input Voltage Range: Operates from 4.5V to 28V for flexible power supply applications.
High Efficiency with Integrated MOSFETs: 148mΩ (high-side) and 78mΩ (low-side) FETs deliver up to 2A continuous output current.
Low Power Consumption: 2 uA shutdown current and 45 uA quiescent current ensure low standby losses.
Fast Startup: Internal 5 ms soft-start reduces inrush current and startup stress.
Fixed 500 kHz Frequency: Simplifies design and reduces external component count.
Eco-mode Operation: Enhances efficiency during light-load conditions.
Frequency Spread Spectrum: Reduces EMI for improved system-level electromagnetic compatibility.
Peak Current Mode Control: Ensures stable and accurate output voltage regulation.
Integrated Protection Features: Includes overcurrent, overvoltage, and thermal shutdown protection.
Hiccup Mode Protection: Prevents damage during prolonged overcurrent events.
Compact SOT-23-6 Package: Ideal for space-constrained PCB layouts with high power density requirements.
