This Buck Converter module is a high-current output power module with 3A (TPS5430) or 5A (TPS5450) capability and a wide input voltage range of 5.5V to 36V. It is pre-configured with multiple voltage outputs (3.3V, 5V, 9V, 12V, 15V, 24V), and by simply soldering the corresponding jumpers, you can switch to the desired output voltage. The theoretical maximum conversion efficiency is up to 95%. The module features a wide voltage output range, with a fixed 500kHz conversion rate, overcurrent protection, and thermal shutdown functionality. It also includes an enable pin, and in the disabled state, it consumes only 18µA. The layout is neat, adhering strictly to power circuit design standards. The materials are robust, with minimal ripple and easy-to-use power output. This Buck Converter module is ideal for student competitions and personal project development.

Feature:

• Overcurrent and Thermal Protection: Features overcurrent protection and thermal shutdown for enhanced safety and reliability.
• Low Power Consumption: With a low quiescent current of 18µA in the disabled state, ensuring minimal energy consumption.
• Compact and Robust Design: Designed with a neat PCB layout and high-quality materials for durability and minimal ripple.

Notes:

• This module is a buck converter, and the input voltage needs to be at least 2V higher than the output voltage for stable operation.
• The module’s heat dissipation is primarily determined by the input-output voltage difference and the load current. Please select and use the power module accordingly, leaving some margin for safety.
• The product details provided are specifically for the 5V output model. When using high-power applications above 10W (e.g., 5V 2A output, 15V 0.67A output), buyers are advised to add thermal paste or heatsinks to cool the chip. With proper cooling, long-term operation should be kept under 30W (e.g., 15V, 2A) to avoid damaging the chip.
