Pololu 6V Step-Up Voltage Regulator U3V50F6

Overview: These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can typically be as high as 5 A. This regulator is available with a fixed 5 V, 6 V, 9 V, 12 V, or 24 V output.

Features:

• Input voltage: 2.9 V to VOUT
• Fixed 5 V, 6 V, 9 V, 12 V or 24 V output with 4% accuracy
• 5 A switch allows for input currents up to 5 A
• Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and under-voltage lockout
• Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load
• Compact size: 1.9″ × 0.6″ × 0.41″ (48 × 15 × 10.5 mm)
• Two mounting holes for #2 or M2  screws
• Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board
