The Pololu 9V Step-up Voltage Regulator U3V50F9 efficiently converts a low input voltage starting from 2.9 V to a stable 9 V output, accommodating input currents up to 5 A. This switching regulator, also known as a DC-to-DC converter, boasts a typical efficiency ranging from 80% to 95%, making it suitable for applications where power efficiency is crucial. The regulator is designed with integrated protections, including reverse-voltage protection, over-current protection, thermal shutdown, and under-voltage lockout, ensuring reliable operation under various conditions.
The compact design of the regulator, measuring 1.9 inches by 0.6 inches by 0.41 inches, includes two mounting holes for secure installation. It offers multiple connection options, such as smaller holes for 0.1-inch header pins and larger holes for terminal blocks, allowing for flexible integration into different setups. The board is equipped with an ENABLE pin, which can be used to reduce power consumption by placing the regulator in a low-power state.
This regulator is part of the U3V50x family, which includes other fixed output versions and adjustable-output models, providing versatility for various voltage requirements. The board's layout includes labeled connections for easy identification and assembly. Note: During normal operation, this product can become hot enough to cause burns; handle with care.
